Tully Hart has always been larger than life, a woman fueled by big dreams and driven by memories of a painful past. She thinks she can overcome anything until her best friend, Kate Ryan, dies. Tully tries to fulfill her deathbed promise to Kate---to be there for Kate's children---but Tully knows nothing about family or motherhood or taking care of people.
Sixteen-year-old Marah Ryan is devastated by her mother's death. Her father, Johnny, strives to hold the family together, but even with his best efforts, Marah becomes unreachable in her grief. Nothing and no one seems to matter to her . . . until she falls in love with a young man who makes her smile again and leads her into his dangerous, shadowy world.
