I’ve now been tagged three times for this, so I’m guessing I’d better actually answer. 
1) Total number of books I’ve owned?
I really don’t feel like counting, but several hundred.
2) The last book I bought?
An Old Fashioned Girl by Louisa May Alcott, on ‘s recommendation. I’m enjoying reading about the brown curly-haired girl falling in love with the rascally redheaded boy. 
3) The last book I read?
Well, I’m reading the above, but the last one I finished is Paladin of Souls by Lois McMaster Bujold. Eagerly awaiting The Hallowed Hunt.
4) Five books that mean a lot to me:
Leaving aside the scriptures, which would take four of my five alloted books:
1) Kilmeny of the Orchard by L.M. Montgomery. So she’s a Mary Sue and he’s a Gary Stu and the plot is melodramatic and predictable– this book was my favorite for years. I even made a porcelain doll based on Kilmeny.
2) Beauty: A Retelling of the Story of Beauty and the Beast by Robin McKinley. My favorite book before Kilmeny. I wore out two paperback copies before I finally found it in hardcover.
3) Pride and Prejudice by Jane Austen. Obviously. My favorite book ever, I can never read it enough. I’ll probably have it memorized by the time I’m 30.
4) Cars and Trucks and Things that Go by Richard Scarry. I love many children’s books, (in fact, it was a close decision between this and I Can’t, Said the Ant by Polly Cameron), but this is the one I remember spending the most time with as a child, and which I still find myself pulling off myself today.
5) The Harry Potter series. Literally changed my life.
