Rosalind is mourning the deaths of both her moms, and Sean is working on his own issues -- the only thing they have in common is a little DNA. When both of Rosalind's mothers die, she moves in with the donor father she never knew. Fifteen, angry, and feeling completely alone, Ros refuses to speak to her biological father, Sean, sharing her feelings only with her journal. But through a series of emails and text messages, Ros and Sean slowly get to know each other. Sweet, comic, honest, and moving, Donorboy is the story of two people who seem to have nothing more than genes in common stumbling toward a shared future. Brendan Halpin has crafted a thoroughly modern take on love, family, and figuring it all out.
