Grateful thanks to all the authors whose books have kept me entertained, made me laugh, made me cry, made me think, allowed me to get lost in another time or another world or another way of thinking for more years than I am willing to put into print in the internet.
Here are some ideas to celebrate:
Write a review (or many)
Tell your friends about a book (or many)
Send a message or a note to an author (or many) telling them you like their books
Buy a book (or many)
