Working with troubled kids myself, it relates a lot to me. The story just gets up and goes from the beginning. A little ambiguity and good character relationships. - Response from a satisfied reader for The Guide.
“Know yourself.” Nicholas Forsythe never knew how important those words were at his first year at Glenoak High School until he met Garron. After he is given a mentor by his parents to help guide him through his rebellious phase, Nicholas is initially skeptical of Garron’s methods. Who is he? How does he know so much about Nicholas without meeting him? As Nicholas works to find the answers to these and other questions about the guiding process, he soon uncovers a deep secret about Garron and the guides: they are from the future, working for the mysterious Determinant Industries in an attempt to fix the perils of the past. All is well with the program, but when a brooding figure from Garron’s time threatens to unravel the very events of history, it’s up to Nick and Garron to not only save their lives, but also the entire fate of the future.
