Princess Perri and the second summer

The sun is shining and the lake is calm. Your second summer on Princess Island is finally here! You will be bunking with your best friend from last summer, Princess Caroline of Ludmilia. The two of you plan to look for the ghost of Violet Grimm, compete for the archery medal, and try to place fifth or better in the Cabin Cup. That is until you find a threatening note under your pillow on your first night away. Someone with the initials "GT" has threatened you and your cabin with "payback." Is the fun over before camp even begins?
