The White Horse Trick by Kate Thompson

The world is drowning.

Freak storms and devastating hurricanes sweep across the countryside. No one has enough food or firewood—electricity is an option only for the tyrannical Commander—and then the Commander begins stealing young children away. Pup's little brother is one of the missing.

Determined to save his brother, Pup confronts the Commander and finds himself “volunteered” for a special force. One that will slip through the barriers of time into a land where the sun never sets . . . just as another boy from Kinvara did long ago. With the future of both realms at stake, the fairies and humans must take drastic measures to stop the destruction. But not everyone wants the human race to survive. . . .

The thrilling conclusion to the story that began in the acclaimed The New Policeman.
