Every Anxious Wave — Mo Daviau

Good guy Karl Bender is a thirty-something bar owner whose life lacks love and meaning. When he stumbles upon a time-travelling worm hole in his closet, Karl and his best friend Wayne develop a side business selling access to people who want to travel back in time to listen to their favorite bands. It's a pretty ingenious plan, until Karl, intending to send Wayne to 1980, transports him back to 980 instead. Though Wayne sends texts extolling the quality of life in tenth century "Mannahatta," Karl is distraught that he can't bring his friend back.

Enter brilliant, prickly, overweight astrophysicist, Lena Geduldig. Karl and Lena's connection is immediate. While they work on getting Wayne back, Karl and Lena fall in love -- with time travel, and each other. Unable to resist meddling with the past, Karl and Lena bounce around time. When Lena ultimately prevents her own long-ago rape, she alters the course of her life and threatens her future with Karl.

A high-spirited and engaging novel, Mo Daviau's EVERY ANXIOUS WAVE plays ball with the big questions of where we would go and who we would become if we could rewrite our pasts, as well as how to hold on to love across time.
