Son Of a Deadly Flower (a Stiles Stilinski/Percy Jackson fic) (TW + PJO)

Stiles was many things, but wholly human was not one of them. His mother before her passing had told him stories about his birth (if it could be called that) and with wide eyes he would listen. Stiles was fundamentally a flower child; his human mother an avid gardener had seemingly gained the attention and affection of the goddess of spring herself. Together they grew a plant that with a little bit of magic gave birth to a half human boy; one Mieczyslaw "Mischief" Stilinski.

Who while raised by is immortal parents, Persephone and Hades, comes to came to find friendship and love with one Percy Jackson while much chaos thereafter.
