PJO things; Camp Half-blood t-shirt - "In a nearby sandpit a dozen high school-age kids and satyrs played volleyball. Canoes glided across a small lake. Kids in bright orange T-shirts like Grover’s were chasing each other aroung a cluster of cabins nestled in the woods. Some shot targets at an archery range. Others rode horses down a wooded trail, and, unless I was hallucinating, some of their horses had wings."
