Seventeen-year-old Camden splits her time between her father, a minor rock star, and her mom, a scruffy hardware geek who designs and implements temporary and sustainable power systems and satellite linkups for off-grid music and art festivals, tree-sits, and attends gatherings of alternative healers. Lark, Camden's father, provides her with brand-name jeans, running shoes, and makeup, while her mother's world is populated by anarchists, freaks, geeks, and hippies. Naturally, Camden prefers staying with her dad and going to the mall with his credit card and her best friend, but one summer, when Lark is recording a new album, Camden accompanies her mother, Laureen, to a healing camp on a mountain in Northern California. After their arrival, Laureen heads to San Francisco, ostensibly to find her lover, but she never comes back. Alone, penniless, and without much in the way of camping skills, Camden withdraws. Things begin to look up when she is befriended by Skinny, a young man in charge of the security detail at the camp who knew her mother as a child. The summer ends and Camden heads back to Toronto to find her dad, and it's only there that she learns Laureen's disappearance is tied, unexpectedly, to the secrets Skinny tried to keep from her for months, until, finally, he couldn't.
