Wow the ending information was just so hard to wrap my mind around. I also can't believe what happened to Dan both during the jump and after. This book was just a whirlwind of emotions. This was my favorite time jump as the 300 is one of my favorite times. I can't wait to see what Dan ends up doing with the information gained as well as how he will handle the time jumps next.

I've said it before about this series, but I'll say it again—this book and series is something I would have loved to have when I was younger. I'm a big fan of Greek history so this was my favorite entry so far. The dialogue is well-written and doesn't feel like it's trying to force “teen speak.” It builds well on the pre-established conflict from the first three books. And the twists! They just keep coming. There were so many tense moments in this book. Can't wait for the next one to see what Dan makes of them. Another great entry in the series.

I received an ARC through NetGalley from the publisher in exchange for an honest review.

5 Stars! I really love this series! This is book 4 in ‘A Jump in Time’ series & it could be a standalone but would be better off being read in order. It’s been a minute since I read book 3, but luckily the author gives info that jog the memory. If you enjoyed the movie ‘300’, this is a book to read. I feel smarter having read this book and it didn’t bore the heck out of me like most history books do. A lot is fictional but it also has many historical facts that are interesting to read about. Did you know Spartan boys were sent away to basically a military school at the age of 7? Entertaining, wonderful main characters, funny at parts, tragic at times, unpredictable, and informative. All in all, totally worth reading, especially for middle and highschoolers but great for adults as well. I usually like romance books but I really enjoy Andrew Varga’s series. He writes so well & everything flows together perfectly. Can’t wait to read the rest of the series! Highly recommend the whole series. You’ll really enjoy it and you’ll feel smarter for having read it! It’s a win/win!
*I received this book at no charge & I voluntarily left this review.*

Learning history and having it brought to life so vividly are my favorite aspects of these books, and The Spartan Sacrifice did not disappoint! I got emotional a few times during inspirational speeches, kind gestures, character deaths, etc. The writing really sucks me into the story.
The romance and Dan's inconsistent intellectual reasoning are my least favorite parts of the books. They're largely realistic depictions, but they make me cringe with either how awkward the romantic bits can be or how implausible some of Dan's deductions or lack thereof can be. I think these may be acceptable to the target demographic (younger readers), as I'm in my 40s so not really who these books are for! I still enjoy the overall premise and especially the history lessons, even though these aren't aimed at me as the audience.
