I gave up on Bear’s Anvil of Stars after a few tens of pages a few years ago and decided recently to give it another try. Now I haven’t enough superlatives to describe it. The author cleverly inverts the weekly Star Trek first-contact story in a way that I’ve never seen before. [To explain would be an injustice to any perspective reader.] To his heroes, space travel is an unwanted adventure, and the evil marauders are the most sympathetically drawn characters. He even manages to cook up an extraterrestrial mathematics I found interesting, integer-free reckoning [how?]. I liked that the alien weapons start out impressively and grow more impressive still, stopping just short of the ridiculous. (The effect on the reader is a bit like giving someone the boxed set and then springing Clan tech on them after a few games.)
Anvil of Stars is the sequel to a novel in which Earth is destroyed and is a better story than its predecessor. Bear needs to get the Earth out of the way before he can really get warmed up, it seems. He did the same with Eon and Eternity, and here too the latter is the better book.
