If this book is all it's said to be, you might want to check out Word Of HonorYep, that's my favorite DeMille book, and I've read most of them. Great story, well told, and I got the impression that it was largely inspired by DeMille's service in Vietnam.
Looks like we have quite the little DeMille fan club here! I've been waiting for the next one. Every few weeks I do a search at Amazon to see if there is a new one to pre-order!
