All 4 published books are good. It kept me going right to the end. (I’d like to know what happens next to the Cullen clan.)
The writing is not Nobel Prize worthy, but the plot is engaging.
I’m looking forward to the next movie. Rumour is Dakota Fanning will play super vampire Jane.

Twilight (The Twilight Saga, Book 1)
Twilight is a series of four vampire-based fantasy/romance novels by the American author Stephenie Meyer. It follows the adventures of Isabella “Bella” Swan, a teenager who moves to Forks, Washington, and finds her life turned upside-down when she falls in love with a vampire named Edward Cullen. …
I immediately started the next Harry Potter book in audio. It’s titled Harry Potter and the Gob of Deathly Phoenix Blood … something like that.
is Dakota Fanning old enough to show up in Twilight as a teenager?
That character in the book is very small. Very young looking. And she’s a good actress.
