"Rosalind had two mommies. Now, thanks to a tragic accident involving foodstuffs, she has none. And Sean, the sperm donor responsible for half her DNA (and nothing else), is taking custody. Rosalind finds herself adjusting to a new life that seems both hateful and surreal - she's an orphan with a new father, surrounded by friends she is beginning to despise and well-meaning adults who succeed only in annoying her." "Sean made a donation fifteen years ago, and his life since has not gone according to plan. Thirty-five, single, and still grieving the loss of his own mother twenty-six years ago, he decides to take on the overwhelming task of caring for an unhappy teenager he doesn't know." "Told entirely through e-mail, instant messaging, journal entries, and other random communications, Donorboy is a comic novel about how these two people learn to converse, cook, write heavy-metal songs, and nail windows shut on their way to becoming a family."--BOOK JACKET.
