This is a terrific resource for learning about the entire Hebrew Bible. It goes way beyond the five books of the Torah and covers the Writings and Prophets in detail, and is one of the only books I've seen that does this. It also lists the 613 mitzvot one by one, with an explanation. For getting a handle on the Writings and Prophets and browsing through all the mitzvot in one place, this book is invaluable.
However, due to the nature of its focus, it's denser and less varied then Telushkin's other huge masterwork, Jewish Literacy. That huge book is a pleasure to dive into and, even for its several hundred pages, read in a few sitting. Biblical Literacy can be a slog to get through and is probably better suited to the study of specific books, chapters, writings, etc.
