One of the best YA mystery books I have read in a long time. Filled with suspense and intrigue.  I downloaded the sample, while waiting for the actual book to arrive.  Big mistake - I got so caught up in the story I purchased the full Kindle version immediately and read the story it in one sitting.

Kelli Sue Landon does a superb job in providing a YA mystery page-turner.  You are expertly immersed in the daily trials of Michelle, a young teen whose new friend, Katie, has disappeared.  She finds it strange and disconcerting that no one at school or at home seems to even care - or even believes her that Katie's Florida vacation is now being explained that she moved there. She, best friend Tami and schoolmate Brad know there is something wrong and go out to discover what happened to Katie?

What was refreshing was Landon wrote the main characters as average teenagers - reacting rashly and even "stupidly". The emotional turmoil of the teenage years is brought forth on so many levels - rumors, gossip, fights, jealously, lost loves, even high-school mean girls, are woven and intertwined throughout the story.  No supernatural insights, or easy solutions. At first, Michelle seems more concerned about the book she loaned the missing girl than what actually happened to her. The fact that the trio didn't intentionally set out to solve the mystery is refreshing.

Landon does an excellent job keeping you hooked, and the suspense doesn't abate.  Excellent piece of YA work, well worth reading and highly recommended.

"Sudden Moves" is the first novel for Kelli Sue Landon. I will definitely be purchasing more of this authors' work in the future.
