One True Loves by Taylor Jenkins Reid

Extended Synopsis

In her twenties, Emma Blair married her high school sweetheart, Jesse. Together, they built a life far from the expectations of their Massachusetts hometown, traveling the globe and seizing every adventurous opportunity. But on their first wedding anniversary, Jesse's helicopter goes missing over the Pacific Ocean. Just like that, the love of Emma's life is gone forever.

Devastated, Emma quits her job, moves home, and slowly attempts to rebuild her shattered world. Years later, now in her thirties, she reconnects with an old friend, Sam, and unexpectedly finds herself falling in love again. When Emma and Sam get engaged, it feels like a hard-won second chance at happiness. That is, until the impossible happens: Jesse is found alive. After years of trying to make his way back to her, he has finally returned. With a husband who has come back from the dead and a fiancé who brought her back to life, Emma is forced to figure out who she truly is, what she wants, and what it really means to love.
