I really enjoyed this first in a series book. Ace Collins likes to write about his interests and (probably among others) his are the 1940's and especially fashion and automobiles of the era. I have now read the rest of the series as it stands (at 10) and I got a little bored with the repetitiveness of his description and year of model of every car used. I also didn't really care anymore that Helen drank her Coca Cola from a 6 oz bottle. Maybe if I hadn't read them successively it wouldn't have bothered me as much. This first one, was the best and I hope number 11 will be the end of the series. I will read it when it comes out since every book ends with a huge cliffhanger, I still need to know what is going to happen with Helen and Henry. As the series has progressed, his characters have taken on almost a comic book aura and the stories have definitely veered towards the sci-fi, fantasy, and super-hero genre. Lots of action if that's what you are looking for.........believability, not so much
