Two Penny Warner Middle Grade Kindle Mysteries, Free to Pre-Order

Two Penny Warner middle-school Kindle edition mysteries are currently available to pre-order for free … as of the date and time of this post. Prices can and do change; you should confirm the price of the book before you 1-click purchase it. The books are scheduled to be published this July, 2012.

One of the titles is Warner's Agatha Award and Anthony Award winner for best juvenile/young adult mystery, The Mystery of the Haunted Caves, which introduced the fearless scouts from Troop 13. Originally published in 2001, a Kindle edition was released last year — and is still available — so we're not entirely sure what's new, or different, about the one coming out in July. (The cover in the upper right is that of the original print edition.)

The second is a sequel to the above title, originally published in 2002, and was also released as an ebook last year: The Mystery of the Missing Mustangs.

When a mysterious clue hints at treasure buried in Camp Miwok's Haunted Caves, Becca and her friends are determined to get their hands on that, too — even if it means sneaking from camp, hanging out with bats, and being threatened by robbers …

And here is the synopsis for The Mystery of the Missing Mustangs: The four scouts are back again for another wild adventure, this time at a dude ranch in the western plains of Nevada. While learning how to care for horses, thirteen-year-old Sierra and her three best friends CJ, Becca, and Jonnie learn about the mysterious disappearance of government-protected wild horses, one of which was supposed to be adopted by their new friend Devyn. When the four friends decide to help Devyn find her horse, they discover it won't be easy, not with a suspicious rodeo owner standing in the scouts' way and leading them to believe someone is stealing the horses and using them for illegal purposes …
