The title gives away part of the plot. What and who might the skinmap refer to? That is a question in a time traveling mystery.
This is a coming of age for the protagonist as he grows into a more formidable person. Kit and Mina were insipid people at best. Kit changes all that by meeting his grandfather.
Time travel and magic intertwine in this story where paradoxical encounters abound. The characters were colorful and the plot was open ended. I would guess a sequel is in the works.
I liked the flavor of the story and the way Mr. Lawhead crafted his plot.I recommend the book.
