Fawcett, H: Emily Wilde's Compendium of Lost Tales

Emily has been obsessed with faerie stories her entire life, but at first she feels as ill-suited to Faerie as she did to the mortal world: How can an unassuming scholar such as herself pass for a queen? Yet there is little time to settle in, for Wendell's murderous stepmother has placed a deadly curse upon the land before vanishing without a trace. It will take all of Wendell's magic--and Emily's knowledge of stories--to unravel the mystery before they lose everything they hold dear.
