I have to disagree, CG. I prefer first books in a series. That's when we meet our characters, their world, and fall in love with them. I have read Twilight so many times.
Leaving NM out, I would think the 2nd books of each series would be my next favorite: Rhage, Dante, & Vaughn. They are all 3 beautiful males. Womanizers (was Vaughn?). They are beautiful males with winning personalities. Mary, Faith, and Tess are women who didn't feel pretty enough too. I'm generalizing a bit.
It's also funny how each series has their *odd man out*: Butch, Sterling, and Judd. None of the men initially fit within their packs. They had to earn their places. Sterling came in in the 3rd book, Judd's book was 3rd, and Butch..well..he played a heavy role in each book.
No offence to CherryKnots, but Lucas is my favorite king. Rar!!!
Squee! Thank you, Nena!
