Slytherin's Son of Poseidon - year 3

Harry was happy. *Genuinely* happy.His relationship with Draco was going well—better than he had ever imagined. They still bickered, of course, because Draco *wouldn’t* be Draco if he didn’t roll his eyes every time Harry did something reckless, but there was something different now. Draco’s exasperated sighs were followed by soft smiles, his sharp words always softened by a brush of fingers against Harry’s wrist or a teasing smirk that sent warmth curling in Harry’s chest.For the first time, Harry felt like maybe—just maybe—he was allowed to have something *good*.But, of course, he couldn’t have a normal year.Because Sirius Black, the most infamous prisoner of Azkaban, had escaped. And everyone seemed to think he was coming after *Harry*.To make matters even stranger, Percy Jackson had suddenly decided to be *very* interested in them.Harry had known Percy was Nico’s half-brother, and they had interacted here and there, but Percy had never really involved himself with their group before. Now, all of a sudden, he was everywhere—sitting with them at meals, joining their study sessions, even showing up at Quidditch practice.
