Waves of Fire || Leo Valdez

Alaia is Percy Jackson's little sister. She's been there since the beginning and has gone on every quest, faced every enemy alongside her brother. She's never given as much of a thought to anything else. When Leo arrives in the Argo II, that changes. She and Leo become fast friends, and eventually, that turns into something new. Whoever said fire and water don't mix wasn't talking about these two.
