Infinity's Web — Sheila Finch

This is the tale of the many possible lives of Anastasia Valerie Stein which come to touch one another through a twist in the fabric of space-time: Ann, unhappy wife and mother in a world much like our own; Val, independent teacher in a timeline of scarcity; Stacey, a free spirit with two lovers, and Tasha, strangest of all, a professional sorceress in a world where the Third Reich rules England. Together they join to confront a force that manipulates all their worlds, and discover a truth that transcends their individual lives.
Finch combines compelling, believable characters, the ancient magic of the Tarot, and quantum physics to weave a spellbinding tale of the infinite possibilities of space and time.
