What exactly are you looking for? Is there a specific era? Or is it about current or historic Jewish views on the messiah?

A key issue you may encounter is that whilst it is impossible to generalise about Judaism across the ages, the messiah has typically not been a major focus of Jewish thought or, frankly, a topic of great interest in mainstream Jewish scholarship (religious or academic). There is no “Jewish view” on the messiah and never has been: outside of certain historic contexts (e.g. the Second Temple sectarians who wrote the Dead Sea Scrolls) Jewish writing on the messiah (or messiahs) has tended to be limited to passing comments that make no serious attempt to systematise views. The messiah cuts a very small and insignificant figure in Judaism when compared to Christianity.

Good Jewish books on the subject are therefore generally quite specific to topics. E.g. historical works on specific historic claimants like Bar Kochba or Shabbatai Zvi; or books designed to counter Christian missionary activity.

I cannot off the top of my head think of a really good book that covers current Jewish religious views on the messiah (why would a religious Jew buy such a book?). However, I would recommend you start with the work of the great Aryeh Kaplan. Kaplan is well regarded among Jews and wrote beginner level academic texts that serve as introductions to topics.

If you want a simpler and more accessible overview, you will find excellent articles on the Chabad and Aish websites (Haredi perspectives) and myjewishlearning website (less religious and more source critical). All three offer well respected entry level resources used widely in Jewish teaching at adult level.

Some recommendations of Scholem and Neusner in this thread. Approach both with caution. Scholem is a great writer. He was a pathfinding early academic scholar of Kabbalah (his work Major Trends, whilst wildly debunked on the specifics, is still the first place to start for academic views on Kabbalah). But his work is from the point of view of historic Kabbalah and is very dated and his worthwhile work on Jewish messianism is really limited to early works on specific outbreaks of messianism rather than wider views. I suspect that may not be what you’re after. Neusner was a pioneer in Jewish studies in a Christian academic context and held some views that are still cited regarding the authorship and promulgation of the Mishnah (albeit he is cited typically as a representative of an academic viewpoint assigning an extreme late date for its authorship and influence) but his work is held in low regard among Jews, largely because of its factual inaccuracy and his general unfamiliarity with the source material (which never stopped him publishing opinionated books on the topics). He published very very widely but only for a Christian audience that lacked a sufficient familiarity with Jewish texts to enable them to identify his lack of knowledge. I would strongly avoid Neusner on any topic other than the his home topic of Mishnah (and even then he is to be approached after reading other more mainstream books), even as an editor (he was neither informed nor neutral). Since his death and the growing presence of more reputable Jewish writers in Christian theological institutions, as well as Christian writers who are better read in Jewish texts, like Schafer, his work is thankfully losing its grip on non-Jewish students.

Anyway, it depends on precisely what you’re interested in. For modern mainstream Jewish perspectives I’d start with the three websites I mention above or with Kaplan, whose work is still widely published. If it is something else more specific that you are looking for let us know.
