Query: 4.5 stars! Interesting "out of time" story.

I am usually not much of a fan of stories dealing with time anomalies, but this one is well done. I have read the author's sci-fi series of Intrepid Force novels, which are much longer and more in depth-- but this story, though shorter, is also quite inventive in plot. I feel it would also interest teen readers, as a large part of its focus involves an occurence that happened when the main character, Jim, was twelve.The story has a good deal of nostalgia for those of us who's childhood spanned through the seventies. You will read about many familiar things from that era as you make your way through the story.The struggle to set things right and establish the correct timeline is interesting in the ramifications that result. It shows, in several instances, that the power of love is strong enough to make huge differences in people's lives.I recommend this book to all readers, and now I am off to read Timothy Wise's new fantasy novel, The Sign of the Sword.
