Mila Austin and her best friend, Lucas Gennery, made a pact: graduate college, return home, and start the rest of their lives … together. One phone call changed everything. Now, Mila is back in Radeno, Texas, lost and alone with an ache in her heart eased by the one person she shouldn't get close to—Lucas’s older brother, Ryan. Grief bonds them, tethers them in a way Mila didn't see coming, and when it's time to let go, she's not sure if she can. Because finally letting go of Lucas could mean losing Ryan as well. Saying goodbye is never easy, but the first time is the hardest.
