Unregenerate!, by David McIntee, has Mel trying to make contact with a newly regenerated Seven, and finding herself and her taxi driver sucked into an illicit Gallifreyan research centre where Tardis brains are transplanted into the bodies of the dying. There was one particularly memorable mental image, when Mel penetrates the evildoers' headquarters on earth and dicovers that it is merely a shell, the real business going on elsewhere. The taxi-driver is a memorable character too. But apart from that, I wasn't wowed by the Doctor saving the day because his brain is just so special (though McCoy plays it well), and not really confident about how it all fits in to what else we know of the Time Lords.
