Mark is 17 years old and trapped in a time loop, and that’s just fine with him. It’s summertime and he’s spending this one infinitely repeating day reading his way through the town library. Then he discovers someone else in the loop with him: the brilliant, haunted Margaret. Together Mark and Margaret set out to find every wonderful, amazing, perfect thing that happens in that one day - a journey that will take them to the dark secret that waits at the very heart of their endless day.

Aria Patel likes stability, certainty, predictability. It’s why she’s so into science. It's why she dumped her boyfriend before they went to different colleges because the odds were that something would go wrong, eventually. In a life that’s already so chaotic, why obsess over complicated relationships and shadowy unknowns when the scientific method gives you direction and a straight path to avoid all the drama. But there’s no avoiding anything when Aria finds herself suddenly falling through parallel universes and there’s no formula that can save her.

There are infinite universes in which Elise never dies. Her best friend, Anna, never has to mourn her or choose between the weight of her grief and the weight of her ambition. Her cousin, Liam, never has to lose another loved one or fight to find purpose in a life that already doesn’t feel like his own. But Liam and Anna do not get to choose the universe in which they live. Across multiple worlds, their paths collide as they wrestle with what it takes to save someone else and how to face love and loss on a quantum scale.
