Margaret Weis and Tracy Hickman, Dragon Wing and Elven Star.
The first two volumes of the Deathgate cycle. I've been rereading some pulp, just relaxing and resting my brain before I tackle the new Ishiguro novel. At any rate, these two are a bit of mindless fun. The cycle of novels lets Weis and Hickman invent all sorts of new worlds and play with them, bringing back old favourite characters for new purposes.
Elven Star is the more fun of the two, with Zifnab and the constant references to other works of fantasy, fiction, and our science. Neither book is taxing, and they're both pleasant enough. I haven't yet decided if I'm going to read the rest of the cycle; it may well take up too much time. 5 more books to read, if I do. I think it'll depend on how my mood is.
