Undaunted (The Secret Life of Cassie Martin #2)
LA Kirk

Now that Cassie understands how Camp Odysseus functions, she steps out of her comfort zone and learns to trust her team. That trust can only protect her so much, though, since secrets continue to lurk outside the team's reach. Cassie must learn to follow her instincts and believe in herself as well as Jay, Noah, Lucca, and Parker.
As a team, they have the power to be an unstoppable force at camp, but only if they work together and grow the connection slowly building between them.
