Little Girl Lost: A Psychological Thriller out of Grimm's Fairy Tales. Only 99 Cents.

Every parent dreads having a child go missing. When the missing child disappears with a little girl  who looks like she came out of the early 1900s, it's even scarier.
Allison and James Price move to the navy-blue forests of Concordia, Idaho hoping to leave behind the chaos of Los Angeles and the painful memories of his indiscretions. Once settled in the picturesque town, where time seems to have stalled and life moves at a slower pace, their six-year-old daughter, Reagan, befriends a mysterious young girl who seems too idyllic to be true with her pressed pinafores, her perfectly curled pigtails. One late autumn evening, as their playdate winds down, both girls vanish into thin air. The little girl said she lived at the end of the street but the only thing Allison and James find at the end of the cul-de-sac is the gaping mouth of the forest. Their little girl, the mysterious playmate—they’re both gone.

Even worse, nobody's heard of their daughter's mystery playmate. Suspicion falls on the parents instead.
