As an American fan of the series with limited exposure to the First and Second Doctors, I found this book to be enjoyable and interesting. One of the things that impressed me about this storyline was the individual attention that is given to the Doctor and each of his companions. Each member of the Tardis crew has a chance to shine in their own right in this storyline. This adventure also gives some details to the Time Lord nature of the Doctor's grandaughter Susan as she contemplates having to regenerate after serious injury. All in all, the purchase price of this Doctor Who Adventure was money well spent in my opinion.
