For a start, Sam is not Sam at all but some dark-haired variant hinted at in Lawrence Miles' Alien Bodies. In Miles' hands this was an interesting idea, a brief anomaly to be pondered over. In Blum and O rman's hands however she comes over exactly like the "older, wiser, more experienced" Sam they tried to create in Seeing I. Dark-haired Sam is unfortunately tedious and predictable. Fitz suffers in the same way... and he and D-H Sam getting it together is unbelievable. Good grief! How pointless.
Fitz changes from a slightly insecure but likeable male into some sort of obsessed shag-monster, alternating between dying for a smoke and lusting after anything female on two legs. Meanwhile D-H Sam--what with snogging the Doctor, sleeping with Fitz and agonising over her past and future--is a typical unstable, neurotic and angst-ridden female all too familiar from Orman's other novels. The Tardis too is made to suffer--like the reader--and the whole plot element about an alien collector of species and his Tardis-like specimen cabinet seemed to have been imported from another novel entirely. Add to this loads of techno-nonsense about bio-data and mythical creatures roaming San Francisco and you have a novel which goes nowhere, does nothing and ultimately bores the reader through too many disconnected pieces of information being thrown together.
A tremendous disappointment after the excellence of Dominion and Demontage. Let's have more books with single word titles that start with the letter "D"! --David J Howe
