The Vanishing Friend — Christine Evans

"A compelling mystery with themes of friendship and bullying, where the reader knows more than the characters, this fifth book in the series can be read as a stand-alone." -- Booklist

When Luca's cabinmate wishes to disappear because of bullying, Raven and Luca use their knowledge of wishes -- and friendship -- to bring him back.

When Raven and Luca go to sleepaway camp, they can't wait to have a week with no parents, no school, and, most of all, no trouble from magical wishes. At Redwood Rescue Farm, they'll take care of animals, meet new friends, and enjoy the awesome scenery. But when Luca's cabinmate vanishes and the camp leaders magically forget about him, Raven and Luca suspect there's more to the camp than meets the eye. Is there a Wish Library among the redwoods?
