Doctor Who books - best to worst

The list author says:
	"Third book I read. Best one so far. Has the fourth and eighth doctors. They don't meet. The Eighth is still in a space of amnesia, + doesn't recognise Harry Sullivan, but they team up... great read!"

The list author says:
	"Starring the 6th Doctor, Autons + Nestene Conciousness. V.slow start... worth it from the middle to the end. Ties in with last stories of Baker's era very well. Highly enjoyable! Killer Tellys!"

The list author says:
	"Terrible start, very boring... then picks up from middle to end. Lots of paradoxes, alternate realities, etc... I like it! Stars eighth doctor (but reminds of fourth). V good."

The list author says:
	"Easily the worst of the four I've read to date, saying that, it was still interesting. Liked the tv movie in 1996? If yes, you'll like this."
