This day changes everything : a novel / Edward Underhill.

Enhanced descriptions from Syndetics:

Dash & Lily meets Ferris Bueller's Day Off in Edward Underhill's new whirlwind rom-com about two queer teens who spend one life-changing day together in New York City.

Abby Akerman believes in the Universe. After all, her Midwest high school marching band is about to perform in the Macy's Thanksgiving Day Parade in New York City--if that's not proof that magical things can happen, what is? New York also happens to be the setting of her favorite romance novel, making it the perfect place for Abby to finally tell her best friend Kat that she's in love with her (and, um, gay). She's carefully annotated a copy of the book as a gift for Kat, and she's counting on the Universe to provide an Epic Scene worthy of her own rom-com.

Leo Brewer, on the other hand, just wants to get through this trip without falling apart. He doesn't believe the Universe is magical at all, mostly because he's about to be outed to his very Southern extended family on national TV as the trans boy he really is. He's not excited for the parade, and he's even less excited for an entire day of sightseeing with his band.

But the Universe has other ideas. When fate throws Abby and Leo together on the wrong subway train, they soon find themselves lost in the middle of Manhattan. Even worse, Leo accidentally causes Abby to lose her Epic Gift for Kat. So to salvage the day, they come up with a new mission: find a souvenir from every location mentioned in the book for Abby to give Kat instead. But as Leo and Abby traverse the city, from the streets of Chinatown to the halls of Grand Central Station and the top of the Empire State Building, their initial expectations for the trip--and of each other--begin to shift. Maybe, if they let it, this could be the day that changes everything, for both of them.

Publishers Weekly Review

For clarinetist Abby Akerman, who plays in her Missouri high school marching band, learning that she'll be performing in the Macy's Thanksgiving Day parade is the push she needs to accomplish her goal. In New York, "you can shout anything you want from the rooftops." So, while on the trip, Abby plans to tell her best friend Kat that she loves her, which will come as a surprise, since no one back home knows that Abby is gay--not even Kat. Grumpy drummer Leo Brewer's band is also performing, but he's much less excited, since being on national TV means that his extended Southern family will find out that he's transgender. When Abby and Leo end up on the same wrong subway train together, they embark on an adventure-filled outing that will change the way they see their lives--and themselves--forever. After a slow start, Underhill (Always the Almost) picks up the pace with the duo traversing Manhattan searching for souvenirs that Abby can give to Kat. Depictions of Abby and Leo's gradually developing friendship--as well as their interactions with the loyal supporting cast--cultivate a safe and affirming space in which two queer teens discover new perspectives. Abby and Leo read as white; Kat is of East Asian descent. Ages 13--up. Agent: Patricia Nelson, Marsal Lyon Literary. (Feb.)

School Library Journal Review

Gr 8 Up--Abby and Leo are about to perform in the Macy's Thanksgiving Day Parade. From different states and different marching bands, the teens are on a collision course to an epic day together that will change their lives for the better. Abby, from a small Missouri town, thinks she might be queer and in love with her best friend, Kat; she's planning to make a grand gesture to Kat while in New York City. Leo, a trans boy, is terrified he will be outed to his extended family when he marches as his true self across their television sets in rural North Carolina. But before these big, life-changing events occur, the Universe throws a curveball, sending them in one direction while their bands head in another. What will the next 12 hours bring for Abby and Leo as they try to navigate the city to get back to where they are supposed to be? As the day goes on, they discover maybe they don't want to get back to reality, because this world with just the two of them is the first time either has felt seen and understood. Underhill is a heartfelt storyteller. New York City becomes a third protagonist in the story, with details of landmarks, smells, and sounds told with accuracy and a lovely turn of phrase. Underhill's writing style is on par with authors like Becky Albertalli and Adam Silvera. VERDICT A wonderful teen rom-com adventure reminiscent of Rachel Cohn and David Levithan's "Dash & Lily" series and Today Tonight Tomorrow by Rachel Lynn Solomon.--Maria Ramusevic

Booklist Review

Does the universe have a say in who we meet or love? In a captivating all-in-one-day tale, that's exactly what two queer teenagers, Abby Akerman and Leo Brewer, are about to find out. When their respective marching bands are in New York City to play in the Macy's Thanksgiving Day Parade, Abby and Leo meet and find they have little in common. Abby, who recently figured out she's queer, is on a mission to declare her love to her best friend, Kat. Leo is just trying to figure out how to keep his entire extended family from finding out he's trans. Though everything goes wrong at first, Leo and Abby embark on a scavenger hunt to find things Abby can use for her confession. Fans of the grumpy/sunshine trope will thoroughly enjoy the dynamic between Abby and Leo, which deepens, in alternating points of view, from mutual frustration to unexpected friendship and blossoms nicely into romance. The cast of supporting characters (Evan is a standout) is layered thoughtfully into the central story. As Abby learns to trust her judgment and recognize the power of her choices, Leo accepts himself more fully and trusts that other people will see him. Pick this up if you love books where the setting feels like a character, but stay for the absolute magic that is watching Abby and Leo fall in love with each other and with themselves.

Kirkus Book Review

A pair of touristy queer teens turn getting lost in New York City into an entertaining rom-com adventure. Abby Akerman's playing clarinet in the Macy's Thanksgiving Day Parade with her Westvale, Missouri, high school marching band, but she's about to do something even bigger. Sure, Abby's nervous about it because she's not out, but she's got this plan. She's giving Kat Wu, her best friend and bandmate, their favorite romance novel--specifically, a "mint-condition, hardcover copy signed by the author"--and also telling Kat that she's in love with her. Drummer Leo Brewer's in New York, too; his Springfield, North Carolina, marching band is also performing at the parade, but Leo's stressed about it. While his parents, sister, and friends know he's trans, his extended family members don't. He'll be outed on national television! When Leo and Abby get separated from their respective sightseeing groups, they meet and agree to find their bandmates (and chaperones) together. But before they can do that, Abby loses the precious book. Seeing how upset she is, Leo suggests they turn this disaster into a scavenger hunt, finding mementos for Kat from the locations mentioned in the novel. With every frustrating, wrong direction they take on the subway, they connect further, each wanting to extend this chaotic day. The tropes of "ugh, you" and "aw, you" are present throughout Abby and Leo's endearingly wild ride through city landmarks. The lead characters read white. A lively, queer romance with flourishes of drama. (Romance. 13-18) Copyright (c) Kirkus Reviews, used with permission.
