Hi, I've been looking for books to read in order to improve my game. I play online micro stakes sit n go's and tournaments (~<1$).
Most of the recommended books for begginers were written in the 80's or 90's, and while I understand that the basics of poker remain relevant, I'd still like to read other books that teach more up-to-date strategies, more in line with the current metagame . I'll still read some of the classics, but I'd like to find a couple more that were published more recently, 10 years ago at most.
Mastering Small Stakes No-Limit Hold'em by Jonathan Little is the only recently published book that seems to be widely recommended, so it's already in my wishlist.

winning poker tournaments one hand at a time is a three book series published in 2008 which is 11 years ago. might be of some interest to you since you play mtt's.

Secrets of Professional Tournament Poker by Jonathan little is two book series by little published in 2011.

The Raiser's Edge: Tournament-Poker Strategies for Today's Aggressive Game by elky and lee nelson published in 2011 is another book.
