War Songs — Susan L. Larmon

Tony has been wounded in a grenade attack in Iraq, unbeknownst to Erika back in the States. Could time travel change his painful experience, and even prevent the car accident that took his parents' lives so long ago? In the meantime, how will Erika, and Tony's sister Kris, deal with his life-altering injury and the resulting PTSD flare-ups? Will they affect Erika's feelings for Tony? "War Songs" is Ms. Larmon's third and final book in her "Time Travel 101" series, following "Swan Songs" and "Spy Songs."
