A anthology of original stories concerning themselves with transmutations, mental and elemental, alchemical and academic. Also, as close to England Swings SF as McCaffrey would ever produce.
Determined space cop Colbie chases charmingly roguish pirate Deverel from planet to planet, into physics-demonstrating trap after physics-demonstrating trap.
The Best of All Possible Worlds edited by Spider Robinson
An anthology build around an ingenious idea: the editor selects obscure stories he likes, then has the authors of those stories select obscure stories they like.
