"Disappointing"
The last of the black cobra books was very disappointing. It was dull, dull, dull. Aside from a brief part near the end when they confront the Black Cobra it just wasn't interesting. The secret of the Black Cobra's identify wasn't much of a secret. I guessed it in book 3.
If you've been reading the series, you'll probably read this one, but not one of SL's finest.
