I have bought "Core Spring 5 Certification in Detail" By: Ivan Krizsan on Kobo, only 5 USD and it's quite good.
Previously I have tried the book by Iuliana Cosmina, but it's too verbose for my taste, I get lost in words, I like only very succinct statement with code samples where needed. Especially I hate "sample applications" developed for the sake of demonstrating the framework... normally they turn into overcomplicated examples where the same patterns are applied "ad nauseam".
