The Forever Enemy

Worse than the first book. I only read it to see if it improved on the first.

Is this meant to be a young teen book?

An interesting plot scenario, but the corny characterisation and dialogue is abysmal.
Various Alien races who all learn to speak English in seconds or the hero learns their language just as fast. Almost miraculous gifts of alien super technology so the hero can save the day... Reminds me of 1950s pulp SF.

I got 50% through and couldn't take anymore.
