Paper Crowns by Mirriam Neal

Ginger has lived in seclusion, with only her aunt Malgarel
and her blue cat, Halcyon, to keep her company.  Her
sheltered, idyllic life is turned upside-down when her
home is attacked by messengers from the world of fae.
Accompanied by Halcyon (who may or may not be more
than just a cat), an irascible wysling named Azrael, and a
loyal fire elemental named Salazar, Ginger ventures into
the world of fae to bring a ruthless Queen to justice.
