The nice folks at Kregel recently sent me a copy of Sue Edwards' recent study guide on the book of Daniel. I am not a big user of guides like this, but a quick scan of the contents suggests that there is some good stuff here. The questions are straightforward and typically relevant to the text. The guide has helpful "digging deeper" sidebars and there are occasional QR codes that link to YouTube videos. If study guides are your thing you might want to take a look at this one. You can read an excerpt here.
