Books in Blood Moon series

The motto of the vampires is that humans have to deal with problems on their own. But when Levka and his friends risk all to save human girls, he is injured and so the adventure begins. A cruise. A human girl who is terrified of water. And a vampire who has targeted her for his mate. But she has some secrets of her own. Forced to take a cruise ship to babysit her foster sister, Caitlin has to face her own demons. But add to that her foster sister's and her friend's antics and Caitlin's inability to use her witch's magic over water and she has little hope to enjoy this trip. Until she meets a wheelchair-bound teen and wants to make friends with him in the worst way. Levka and his friends make a hasty retreat from Dallas before the vampire elders stake them for getting involved in human affairs--again. But when he meets Caitlin on the cruise ship, hating that he's so weak after being injured so severely that he has to use a wheelchair, he finds their troubles have just begun.
