The Trials of Miriam Johnson.

Miriam Johnson makes her escape into the unknown forced to use a faulty time-travel transporter and lands on a desert island. She ‘transports’ from the island and meets historic characters, she even finds herself in the presence of Marco Polo in the court of Kublai Kahn. In the second part of the story, married and pregnant, she is curious about her and her child’s future. Compromised by more anomalies, she lands in parallel worlds, meets up with two strange ladies, and loses her time transporter; in both cases her fiancé, Charles Wright sets off in pursuit, plagued by time-warp anomalies.
