Watermark — Krissi Dallas

I stared at her in frustration. 'What is with you?!' I exploded. She was not acting like my best friend. Like my Morgan. 'You've been so different this summer, and I don't get it!'
'Well, you've been different too! People change, you know,' she snapped back.

Relationships on the White Island are volatile, and Whitnee, Morgan, and Caleb aren't sure who they can trust--even each other. Politicians are lying, history is being rewritten, and motives are questionable. Whitnee sets out with Gabriel and a band of rebel spies to take back the enemy's biggest weapon--Whitnee's father. However, a shocking turn of events proves once again that the Island's secrets have the power to destroy more than just the truth. Separated from her friends, Whitnee battles her own fears in order to survive and protect the ones she loves. But when Morgan's illness finally comes to light, Whitnee faces a decision that could alter her future--and Morgan's--forever. And whether she ultimately stays on the Island or leaves might not be her choice after all.
