I'll say this, for 99 cents Sleeping Kings offers a story filled with action, adventure, and the slightest hint of romance for an unbeatable price. If you have an e-reader or don't mind reading books on your computer, I highly recommend the first book from John Prentice's Dark Force series.
Nicola "Nik" Roscoe didn't expect to find herself in France, but she refused to move to the U.S. with her mother, and her father's work required a move to France. Nik, a tomboy and bit of a rebel, likes being with her dad, but her new life in France leaves much to be desired. That is until Nik and her class go up into the mountains and Nik falls into a cavern where she meets King Pedro, a man who's been dead for a number of centuries. With King Pedro's guidance, Nik learns she has special powers that can help save her father and her new friend Daan.
The mix of action/adventure and hints of romance worked really well for me. It's not so romantic that boys will hate the book, but there's just enough romance that teen girls will want to keep reading. They'll be dying to know if Daan and Nik hook up. The writing is gripping and keeps you drawn to the story from beginning to end. As this is the first book in a series, there's definitely more to come and I eagerly await future books!
I really enjoyed this story. One thing that I should mention is that the author is clearly British and therefore uses terms that some teens in the U.S. may not understand. My mom's English, so I knew everything, but terms like "boot" (trunk of a vehicle) are things my kids have had to ask me to clarify in the past. There are a number of sites that can help teens who need words clarified, or drop me an email and I'm happy to help.
