A novel of how family happens?whether you like it or not

Elaine and Carson Forsyth have returned to the tree house?Elaine's childhood home, a cabin nestled high in the branches of two oaks beside a North Carolina lake?where forty-nine-year-old Carson has chosen to spend the waning days of his life. As Elaine prepares for a future without her beloved husband, their solace is interrupted. Carson's mother, Greta, has set loose a neighbor's herd of alpacas and landed herself in police custody. While Carson, remarkably, sees humor in the situation, Elaine can only question what her obligations are?and will be?to a woman who hasn't spoken to her in more than twenty years.

In the wake of Carson's death, Elaine and their grown son, Mick, are thrust into the maelstrom of Greta, the mother-in-law and grandmother who never accepted either of them. Just as they are trying to figure out their new roles in the family, Mick uncovers unexpected questions of his own. A long-ago teenage relationship with a local girl may have left him with more than just memories, and he must get to the bottom of Greta's surprising accusations that he's not Carson's son at all.
