Thirteen-year-old Katy thought she was happy with her life in North Carolina, stargazing on the back porch and camping on the Blue Ridge Parkway with her dad. But when her mom, Liz, invites her to Scotland, Katy realizes how much she's missed having a mother. Katy meets her wild Aunt Claire, whose boyfriend throws punches first and asks questions later, and without warning, the three women find themselves on a road trip through the Highlands to escape a dark secret that could shake up Katy's life, and her relationship with Liz, forever.
