Wiklow

Cami Ramirez has been missing for two months. When four of her friends return to their hometown for summer break, they find she did not disappear without a trace. She left them a trail of clues. The first is Wiklow, a book they made as children, recording all their adventures with strange creatures in odd places. The second clue is a note from Cami beckoning her friends to follow her.
Follow her to Wiklow.
Was it more than childhood imagination? Was it all real? And most importantly, can they go back?
