Philter of Fate: Book 1 of the Witches of Jeru

Maria isn't your typical sixteen year old, she has a secret; she's a witch. An attempt to use Magic to get a chance to date her high-school crush backfires and a prophecy tells her she has until the next solstice to find her one true love or risk losing her soul. But who might it be? Xavier, who seems to fit the prophecy or Andrew, who doesn't but won her heart? A mistake would be fatal.
