Flux by Jeremy Robinson is an engaging sci-fi book that takes you through time. Good parts were the connection between characters and historical accuracy. I found more difficult/not-expected the superhuman characters and what they were doing in the story.

Here is the synopsis: “International bestselling author of The Others and Infinite, Jeremy Robinson combines science, action, and strong characters to create an ever-changing landscape that explores the past, the human condition, and the lengths people will go to save those they love.”
