This is a delightful collection. Not because every contribution is delightful; for example, I would be surprised to hear, based on his contribution, that Eoin Colfer had ever seen an episode of Doctor Who, or had ever written for anyone over the age of three and in possession of a human brain. No, it is a delightful collection because the other stories collected are so delightful in so many ways.
Where to begin?
Two, Ten, and Eleven are my favorites here - though having Neil Gaiman write a story for a collection like this is really cheating, because Neil Gaiman is so brilliantly Neil Gaiman, and references Kurt Vonnegut so very subtly and cleverly, and almost made me cry with the simplest of statements about the potential of a species, and the potential of a single child. Cheating, I tell you. It's more fair to discuss what each of the other writers has to offer.
Derek Landy: I was reluctant to start this one, because while I love the Tenth Doctor, I have some difficulties with Martha Jones, namely Mr. Otherwise-Brilliant Davies' lame smart-woman-gets-stupid-over-a-man storyline. To my delight, Landy ignored that storyline, and instead gave Martha the rich literary background that any intelligent, well-educated person must have. Including the turkeys. He also captured Ten's ridiculous voice perfectly. I laughed out loud more than once.
Charlie Higson: Nine is my Doctor. This is not Nine. Close, but no cigar. He's got the ears and the grin, but the depth of character that captured me, the darkness, the ill-concealed grief and rage, even the childlike fascination with the universe, all are missing. However, the one-off companion Higson creates is completely, brilliantly unique. Hats off to Higson.
Alex Scarrow: Great Eight. Great story, great companion, nice and creepy and cleverly done.
Malorie Blackman: Daleks as you have never ever seen them, and likely never will - though Gaiman, all unknowing, gives her a nice hat-tip. A lovely if occasionally uneven Seven & Ace story with lovely, tragic original characters.
Richelle Mead: First person Peri POV. I got a better feel for who Six and Peri are than I ever did from watching an episode of theirs. Points for bringing back a classic and tragically underused villain.
Patrick Ness: Bit of a mess, but decent enough. Five and Nyssa, mostly from the POV of a young Jew in wartime New Jersey. Points off for inappropriate use of 'fortnight' - an American character would never even THINK that word.
Philip Reeve: Four and Leela at their goofy best. A bit too much like Face of Evil, with rather unnecessary inclusion of the Eleventh Doctor.
Marcus Sedgewick: Classic Three and Jo Grant, with just a touch of UNIT. And Odin. Good Viking fun.
Michael Scott: A delight. Two and Jamie, the Master, and a pantheon of Lovecraftian evil. Bagpipes save the day. I'm a sucker for stories with music in them, especially serving a critical function. This one is very well done.
Recommended for fans of the whole Who, or at least numbers two through eleven, and Gaiman's story is a must-read. Highly enjoyable.
