Dreamsnatcher - Dreamwalker, #3

Lexa has spent the past five years training the princess of Teltania in dreamwalking, but with Taryn's eighteenth birthday approaching, the girl has increasing royal duties and Lexa is getting ready to retire yet again. This time she's looking forward to settling down and sailing with Sir Neil Duram-until his ship barely survives a raider attack. The raiders have been hounding Teltania's coast and their victims are falling into comas.
With Neil's crew at risk, Lexa sets out to find a cure. But things aren't what they seem. She discovers that the comatose have been snatched from their dreams and stolen into the dreamscape. The scattered cases soon become a potential plague, and Lexa has to find the connection between the waking world raiders and the dream snatchers. Is there a third dreamwalker out there, or something much more sinister? Lexa's desperate search for answers will drive her to the edge in order to save everything she cares about.
