Ironspark

A teen outcast must work together with new friends to keep her family and town safe from murderous Fae while also dealing with panic attacks, family issues, and a lesbian love triangle in C.M. McGuires's kick-butt paranormal YA debut, Ironspark.
For the past nine years, ever since a bunch of those evil Tinkerbells abducted her mother, cursed her father, and forced her family into hiding, Bryn has devoted herself to learning everything she can about killing the Fae. Now it's time to put those lessons to use.
Then the Court Fae finally show up, and Bryn realizes she can't handle this on her own. Thankfully, three friends offer to help: Gwen, a kindhearted water witch; Dom, a new foster kid pulled into her world; and Jasika, a schoolmate with her own grudge against the Fae.
But trust is hard-won, and what little Bryn has gained is put to the test when she uncovers a book of Fae magic that belonged to her mother. With the Fae threat mounting every day, Bryn must choose between faith in her friends and power from a magic that could threaten her very humanity.
