Rowan Roth aims to be the star of her high school, and with only a day left until official graduation she’s feeling nervous; she’s focused on trying to outdo her frenemy, Neil McNair, who has been her rival since freshman year. The two have sparred at everything — from essay contests to collecting the most cans for the environmental club — but when Neil is named the class valedictorian, relegating Rowan to salutatorian, she is shocked. Realizing that this will be her last opportunity to outdo Neil once and for all, she sets her sights on winning Howl, a riddle and scavenger hunt game where high school seniors are sent around Seattle with clues to decipher, and the winner receives a monetary prize. After Rowan overhears classmates bashing her and Neil and vowing to finally beat this dynamic duo at something, Rowan realizes she must team up with her enemy in order to win the game. As the two rivals explore various locales of Seattle, Rowan learns about who Neil is outside of all the academic and extracurricular competition; she begins to wonder if perhaps she’s falling for her nemesis.
The book uniquely depicts the city of Seattle from an insider’s perspective, which gives readers a textured look into these character’s lives. Both Rowan and Neil are Jewish, although neither realized it until this last epic day as they’ve been caught in their academic battles. Rowan is a self-aware protagonist; many readers will empathize with Rowan’s inner turmoil surrounding her fear of being judged by family members and friends for her passion for reading and writing romance novels. Ultimately she must decide whether or not to reveal her truest self and face the possible judgement of those she cares about. The cast of characters is composed of complex individuals, with relatable traits and flaws. Additionally, the book is peppered with artifacts from Rowan and Neil’s adventures around town, including receipts, Howl clues, and text messages between Rowan and Neil, as well as segments from Rowan’s parents’ books — an accomplished author-illustrator team. Today Tonight Tomorrow is an entertaining, engaging read on coming-of-age and becoming comfortable in who you are.
