Watching children play and invent whimsical games of fantasy is one of life’s great joys.  But what if you could actually see your child’s imagination as it unfolded?  And what would you do if your child’s imagination suddenly became dark and threatening? 

Burned-out and broke, twenty-two-year-old single mother Anna Jennings moves to her grandparents’ rural home for the summer with her four-year-old son, David.  The sudden appearance of shadowy dinosaurs forces Anna to admit that either she’s lost her mind or she can see her son’s active imagination.  Frightened for David’s safety, Anna struggles to learn the rules of this bizarre phenomenon and how best to protect him.  But what she uncovers along the way is completely unexpected: revelations about what her son’s imaginary friends truly represent and dark secrets about her own childhood imaginary friend.

Living right next door is Jamie Presswood, Anna’s childhood friend who has grown much more handsome and hardened than the boy she once knew.  Jamie reminds her of simpler times—Ferris wheels and sparklers, picnics by the river, and Neapolitan ice cream—but due to past regrets and the messy lives they’ve since led, rekindling their friendship proves easier said than done.  Between the imaginary creatures stalking her son and her tumultuous relationship with David’s biological father, Anna doesn’t have any room left in her life or her heart for another man.  But as David’s visions become more persistent and threatening, Anna must learn to differentiate between which dangers are real and which are imagined, and who she can truly trust.
