Unlikley - Kingdoms Gone, #1

In a world where magic has been broken, where the last remnants of power hide in pockets of magical space, a fairy godmother and a trickster look for justice and find... love.  Satina wants only to be helpful, to grant her wishes and to heal the rift between magic and the mundane world. When she arrives in a town under siege by a magic-hungry gang, the last person she expects for an ally is the local scam artist.
Martin is half imp and all annoying, but he draws Satina to him as if she's under a spell. For the first time in her life, she wants to make a wish for herself, but the heart she wants to win belongs to the one person in all the kingdoms who knows she's a fraud. If she can convince him to help, they just might be able to save their town, to keep magic, safe, and to prove that love still grows in the shadow of destruction. If she can't, then more than just one town is at risk.
Satina could lose the only thing she's ever wanted enough to make a wish.  First in a five book, fantasy romance series.
