First off, this is part of a series with another book following soon(ish).
This story doesn't hold back, if you're looking for an adventure and are a fan of time travel - this is the series for you. I know, I'm the first to admit that it's so hard to find a story where the plot can get lost or you feel like you've lost what time you are in. The truth is that Mark is totally able to transition eras in a really seamless way. You almost feel the words transition you so effortlessly that it just works perfectly here.
Add it to your list if you're one for adventure and in general are a fan of fast paced stories that grab your attention and refuse to let go. You will be captured in the first page and crying for more by the last word.
