If I had to choose two of my favorites. #1 would be Stanford Wong’s Sharp Sports Betting. It’s still a classic book for serious sports betting. The math portions are very well written and easy to understand. Some of the content is outdated, but for the most part, it's still a very useful book.
Another one I really liked is Matthew Hilger’s The Poker Mindset. Not directly related to sports betting, but the mindset aspects discussed in the book (such as focusing on long term performance rather than short term results), are relevant for sports betting as well.
To find more books I’d simply do an amazon search for “betting books” and read the buyers reviews. Also, gamblingsitesonline has a good article that breakdown some of these books and a couple more
