Summary: In a world where vessels are rare and necessary treasures for powerful mages, serving boy Adam finds his world turned upside down when he's called forth to take his half-brother's place as vessel and bondmate to Michael, Archmage of Water. Will this be the doom Adam expects it to be? Will the bond even take? And, for the love of the gods, will anybody ever tell him why it's so vital that he begin submitting to the bond practically before he even shakes off the dust from travel?
