Book 1 is The Lies of Locke Lamora and book 2 is Red Seas Under Red Skies. These novels are full of witty conversations, intricate schemes to rob rich people, epic friendships (think Frodo and Sam from Lord of the Rings), humor, and crazy plot twists.
If you like reading books with a more advanced vocabulary and dry humor like Pride and Prejudice you will appreciate the language in these books.
Some fair warnings: there are NOT always happy endings in these books. And if you are trying to read a book with romance, read something else. And the first book, jumps around a lot in the timeline. The main character will be a kid, then it jumps to him as an adult and his life now, and will do periodic flashbacks. I was confused at first, but it is definitely worth reading on. And the third book, has been scheduled to be published a few times and has been pushed back a year at a time. (The author has been suffering with a divorce and depression according to his website) So if you get frustrated waiting for the next book in a series, just be aware of this.
That said, I loved the sheer guts it took to rob people the way they did (think Neil Caffery in tv show White Collar, a con man who pulls off these crazy ideas) and the twists and turns of the two books. I highly recommend Scott Lynch.
