Timeless is the last book in the Parasol Protectorate series and it certainly is on par with the rest of the series. The whole series actually has been steadily good throughout. 
 This time everything we've learned is coming full circle. While Gail Carriger doesn't come right out and answer every single question / mystery that has arisen over the course of the series she has certainly given us all of the most important information. 
 Timeless takes place about three years after the events of Heartless. Prudence is a toddler wreaking havoc on Lord Akeldama's household and everyone has gone about their lives and daily routines with little excitement. After all the events of the previous books I think Alexia was content with things being quiet for a time. But, just when the quiet seems to be getting a little dull, Alexia is summoned by the vampire hive queen in Alexandria to Egypt. Not only is Alexia summoned but Prudence is similarily summoned as well. So of course Alexia heads out with baby, husband, and the Tunstell acting troupe in tow. 
 I have been increasingly amazed in this series with the duplicity that occurs between the characters. There are those that I build up a trust for and then they turn around and have an ulterior motive. I applaud Carriger's writing in that even those characters who have done wrong in the past (or present) are still characters that I like. She's built them up so well. 
 There are plenty of surprises and twists and turns that we've come to expect of this series. I was a little worried that we were thrown three years in the future instead of keeping with the original timeline. But after the first few pages I understood that this was the best. Prudence is a great little character and it was wonderful for her to actually be able to walk and talk and cause havoc. It reminds us of the parents that she came from and gives us a little inkling of what to look for in her own spin-off series in the future (Prudence). 
 I liked the ending and while it's sad that there will be no more Alexia in the foreground we will still get stories in the Parasol Protectorate world. Until Then!
