I absolutely love the In Times Like These Time Travel series. This detective series is a spin off from the original books. It is done in classic detective series style with a time travel twist. I previously read the Kindle versions of the books and really enjoyed them so was glad to see this combined set. It was a great listen and just as good the second time through. These books are standalone so it isn’t necessary to read the original series to understand what is going on. Still, I recommend starting with In Times Like These and then reading/listening to this series to get the most out of it.
