Hey BlackJaqk (nice username by the way!),
Based on your post it's hard to tell what kind of magic you are into, so I will take a look at my bookshelf and list some that I think would be of good interest to you (if you are into card magic):
Royal Road to Card Magic by Hugard and Braue
Card College Series by Roberto Giobbi
Expert Card Technique by Hugard and Braue
Card Control by Arthur Buckley
Dai Vernon's Inner Card Trilogy
One Degree by John Guastaferro (there are a few card tricks in here that are simple and get killer reactions)
The Five Points in Magic by Juan Tamariz (more about improving your performance and making connections with your audience)
Those are just a few that will surely give you a TON of material to practice over many years of getting into card magic in general. Also, Jason England has a free video here on the site with his definitive reading list of what to read, when, and why. You can view that right
HERE.
Hopefully this was able to help you out if you are interested in card magic!
