The last two books are Wicked and the sequel which is Son of a Witch both by Gregory Maguire. My curiosity has been piqued when my high school did their rendition of Wicked so, when I saw this, I snagged it immediately.
Wicked (Powerbooks) Php349 (but I bought it on sale so I paid a little bit less than Php300)
Son of a Witch (National Bookstore) Php299
Have a Little Faith (National Bookstore) Php295
So, I'm putting my book buying on a pause because I have a LOT of books in line waiting to be read. So, no book-buying in the near future!
