Disclaimer: Even though I think you know this by now, I'm not Rick Riordan.
Poseidon's favorite son
Even though he's been kicked out of every NYC school
Riptide never leaves him
Can easily anger Dionysus (who can't?)
You'll never see him with Rachel. Ever.
Style of poetry: acrostic
Sorry 'bout that last line. Diehard Percabeth shipper here.
