I find it very difficult to read the same book twice. So when it happens, its very rare.
Most of the time rereads were an occurrence of college related assignment. Of the books I've reread at least two or three times for school purposes. : Dracula; Frankenstein; and 1984
, which was made me happy considering its my favorite book of all time.
And off the top of my head, the only other book I have reread more then once, for other then school related purposes was Watership Down
The ironic thing was I purchased the essay anthology This I Believe
with the specific purpose to reread during times of stress and emotional difficulty. Especially these days, they would be much appreciated. However, I have yet to take up the book from its bookshelf position.
