What book would suit me best?

Hi, check this site out: http://chesstempo.com/chess-tactics.html it's free and let you work your tactics :)

Chesville has uploaded a free tactics book  (1001 Winning Chess Sacrifices and Combinations):

http://www.chessville.com/downloads/downloads_tactical_exercises.htm

As in real books, these books are great basic tactic books:

- Chess tactics for Students - John Bain

- Winning chess excercises for kids - Coakley (a lot of masters recommand this book for all people, so don't get fooled by the title)

- back to basic: Tactics - Dan Heisman

I also strongly suggest reading these articles regarding tactics:

Sadly i don't know any dutch tactics books, so i can't recommand any of them. I hope this helps. Please let me know wich path you will follow, as i'm still working on my tactics as well. Always interested to know what works for someone and what does not. 

Best chess book I ever read was Bronstein on the Kings Indian - positional look at the opening.  Amazing read, brought my game on more than I can say.

Thanks, I'll check some of this out after my exams!

Being a tactical player myself, Attack with Mikhail Tal is a book I would recommend. I maybe a bit subjective since Tal is my favorite though.
