Shape of Memories by Kristofor Hellmeister

Alpha Grisham is used to authority. After years of being raised by an overbearing father, Tyler Grisham is now in command of his own vessel, The Mayflower. His life soon spirals out of control, however, when he crash lands on an uninhabited planet--UP-117. It is here Alpha Grisham encounters a being that takes the shape of his most intimate and most powerful memories, including that of his estranged wife, his domineering father, and that of his dead childhood friend. But, there is a memory that he does not want to encounter--a memory that begins to hunt him down.
