Hi,

I have finished all of the Kanzen Master reading book for the JLPT level 2, and was wondering if anyone can recommend a similar book produced by a different company?

Uh, there are a ton of them. I would just browse through the sample pages until I found on ewhich looked good. That, or do past tests.

Yup, I would also recommend going through the past exams. Then maybe, just to practice, you could also set a timer and actually do one in the same amount of time in an actual exam.
Also, maybe you can try looking at JLPT N1 Kanzen Master to see how much you can recognize. Will you be studying for the N1 soon?
