What if: In 1946, a genetically-tailored virus from outer space was released in Earth's stratosphere, killing many but giving super powers to others.
Summary: The many effects of the virus during the ensuing decades as super-heroes and super-villains appear all over the world. Curiously, history isn't altered all that much.
Series note: Long-time ongoing series of books, with as of late 2018, volumes one through 27 published or announced. Most are either edited or co-authored by Martin, but volume X gives sole cover credit to Melinda M. Snodgrass, volume XII to Victor Milan, and volume XVII to John J. Miller. (Note that due to change of publishers partway through the series, the cover numbering of volumes resets.) There are related comic book mini-series, one by Gregory Wright and Nelson Yomtov and another by Daniel Abraham and Eric Battle. There are also three role-playing sourcebooks for the GURPS role-playing game system, John J. Miller's GURPS Wild Cards, Kevin Andrew Murphy's GURPS Aces Abroad, and John J. Miller's Wild Cards: A Mutants & Masterminds Campaign Setting.
Comments: Although called "mosaic novels," these volumes may be considered shared-world anthologies. However, individual entries for each story are not included in this bibliography. Within the overall series, plotlines are structured in (typically) groups of three volumes.
