"Dark Sun" by Richard Rhodes is probably better (and more
entertaining). It describes the Teller-Ulam mechanism in some
detail. I will point out that, if the description of the initial Ivy
Mike test is to be taken as an indication, it actually requires quite
a bit of effort to put together such a thing -- one need worry about
amateurs building fission devices, but probably no fusion...
