Trek Books

Can you recommend me some Action/Medieval/Sci-Fi/Crime books?
Looking for some nice books to read, i like mostly action books. Anything from the crusades in medieval times such as Pilgrimage to Sci-Fi action adventures such as Deathworld or Star Trek books.
Also, i would like it if the books contain some sexual scenes (just like Nicholas Sparks or Christopher Pike). IT helps to keep things alil feisty and romantic. Any recommendations?
Well your request is rather broad, but I think I have one that you will love because it covers Action/Medieval/Sci-Fi all in one!
The Cross Time Engineer
(The Cross Time Engineer series – aka The Conrad Stargard series)

Its even better if you are POLISH as the main character is as well!
This was an eye opening look at how technology could transform a society, and gave some very good descriptions of simple improvements that lead to our own industrial revolution.
I guess you can tell I loved these books.
Similarly you might enjoy these as they are novels that mix action, ancient societies, and Sci-Fi. These have a bit more female intrigue but it is not explicit.
“The Forge” by S.M. Stirling.
(the General series)
“Island in the Sea of Time” by S.M. Stirling.
(the Nantucket series)
“An Oblique Approach” by Eric Flint
(Belisarius series)
Most of the books that include medieval themes are more properly qualified in the Fantasy portion of the general category of “Fantasy & Science Fiction” section of your book store.
