Good series. Book 4 was probably my least favorite and Book 3 my favorite. Book 5 felt rushed to me there were some big time jumps and things happen fast in the story. I enjoyed the trips back to earth in the first couple books but they basically disappeared by Book 3. Worth the time and money just would have preferred more story especially for “side” chars the 1 hour “goodbye” epilogue left me with mixed feelings about the series
