This book is the first Doctor Who one that Craig Hinton has written in a considerable time. It's very good, but that's what you'd expect from the man who wrote the best Virgin Missing Adventure 'Millennial Rites'
The Quantum Archangel is a sequel to the television story The Time Monster and sees the return of several of the characters from that story. The Master is dying, with the Traken source nearly exhausted, he is searching for a way to extend his lifeforce and that is where the experiments of Professor Kairos come in, for he has adapted the TOMTIT technology of the Time Monster into the more powerful TITAN array which has the power to penetrate Calabi-Yau Space - the domain where the Chronovores subsist.
The Quantum Archangel is an excellent entry into the Past Doctors series. It starts off wonderfully reminisent of Millennial Rites with some of the locations being simillar and being only a few years after the events of that novel. The Master finally gets to be really nasty to the 6th Doctor on his own right without the Rani or the Valeyard around to spoil it for him. Like Millennial Rites, the book is split into two sections, although the split is not as drastic as it was that one.
The Quantum Archangel is well written, with an ingenious reworking and expansion of the Time Monster's plot. The book becomes a little confused at one point towards the end when the Chronovores strike, but aside from that it's a really good book.
Shame about the awful cover though.
