This review is from: Doctor Who: Illegal Alien (Paperback)
Illegal Alien is the first 7th Doctor PDA of the BBC Books range, the first book in Mike Tucker and Robert Perry's self styled "Series 27" and was infact based off an actual script in consideration for the run.
The premise of Illegal Alien is, well I don't actually know. The Doctor and Ace stumble upon Cybermen in the war torn streets of London 1940. The reasonings are still not clear, but it makes for a fairly entertaining read nonetheless. The book keeps your interest all the way through and the pages seem to fly by.
Character wise Mike Tucker and Robert Perry have got the 7th Doctor and Ace down to a tee. The supporting cast seem to be cliched, or two dimensional but it doesn't detract from the enjoyment. The only bad thing is the treatement of the Cybermen, for the most part they are pawns to other people and not at all terryfying. The Cybermats are scary, but there use seems to diwndle as the book goes on.
In short, Illegal Alien is a perfectly fine Doctor Who novel and one I heartily recommend to old and new fans alike.
