Hi Bookwombs

Thinking to buy a book as a gift to one of my girlfriends, but cant decide what book to buy.
As she was recommended a few books for me to read (below), could you suggest nice books similar to below category?

a) The Lost Symbol - Genres: Novel, Thriller, Mystery, Suspense, Crime Fiction

b) The Silence of the Lambs - psychological horror-thriller

c) Alchemist, Adultery of Paulo Coelho - Genre: Fiction

Thanks in advance!

Thanks all for the recommendation!
