There were only a few problems I had with this Fourth Doctor story set during the "Key to Time" series. The first was it really didn't feel like a Fourth Doctor tale. Some of the scenes in this book were so bizarre that you had to put it down and say, "What the heck! ". The other was the portrayal of the Doctor. Most of the writers tend to overly portray the Fourth Doctor as an imbeccilic clown. Although, he is very well known for his "Teeth and curls" I would love to see a writer go deeper into the Fourth Doctor's character. Now onto the good. Besides those pretty minor flaws, I thought there were alot of interesting ideas in the book. The Doctor has to put his mission for the White Guardian on hold as he and his new companion Romana accidentally stumble apon a expedition led by a mad man to open a tomb and release an ancient god known as Valdemar. If this mad man is successful, the universe as we know it will cease to be. The author's portrayal of Romana is very good as he focuses on not only her annoyance of having to put up with the Doctor's eccentricities, but also learn how to cope with the life outside the comforts of Gallifrey. This books tends to be a bit slow at parts and the supporting characters tend to be on the annoying and unlikeable side, which could have possibly been the authors intentions. But if those set backs don't bother you in the least, I highly recommend you pick up this book. It not bad.
