This takes place right after the HoO series.

The two camps (Camp Half-Blood and Camp Jupiter) are finally joining forces. You got to the camp and passed out on Half Blood hill. The next thing you know you're waking up in a medical cot somewhere you don't know.

A boy with blond hair (Will Solace) was about to rush past before realising you're waking up.

"Oh, you're awake," he said with mild relief as he comes over to check how you're doing.
