good pot limit Omaha books

[bengali]

Ive played a bit of Omaha high pot limit online, and even though I feel I have a grip theres still a feeling that there is much more to learn.
Im looking into buying books but there doesnt seem to be much written on the subject. the tom mcevoy and cloutier book had 2 reviews, one awarding it with 5 stars and the other one just one star and its hard to know which one to trust.

so the question, dear 2+2ers, what books are worth the trouble of buying?

all help appreciated!
