Show jumper Georgina Bloomberg will release Off Course, the third book in her series of teen novels, on Nov. 13 via Bloomsbury Publishing World Wide. The book, co-written by Catherine Hapka, follows The A-Circuit, released in May 2011, and My Favorite Mistake, released in February 2012.

Off Course chronicles the adventures of three elite teenage riders competing in the hunter/jumper world. Bloomberg, who is the daughter of New York City mayor Michael Bloomberg, brings plenty of experience to the series, having competed on the A circuit as a young rider.

A portion of the proceeds from the book will be donated to Friends of Finn, a charity that works with the Humane Society of the United States to help stop puppy mills.
