you can certainly read many books about assembler but you can't understand them at once. imho the best way to learn masm32 more quickly is a practice by debugging any easy application (e.g. executable files from icezillion's tutorials). by this way you can understand how to work executable file on binary level.
i advice you to read ricardo narvaja's tutorials (20 lessons sufficiently) "Introduction to cracking with OllyDbg from zero"
where you learn about OllyDbg debugger. in the future you'll able to understand any source code written with masm or another language.
