I visited Harper-Collins website and found a great book club source idea. I don't know how long it has been in existence, but it is new to me. It is a great book club idea.
The publisher's website allows you to view the whole content of a book for the entire month for free. This month they are featuring Space Between Us by Thrity Umrigar. Each month they will feature a new book title for the whole month. This is a great source for clubs to sample the books before getting to the meeting.
