The Eternal Tide
was indeed awesome. It felt like a huge event.
As for the Voyager books, the premise is a little goofy (after all that effort to get home they go back?!?) but dammit, it's Star Trek and Star Trek is a little goofy and anyone who tries to deny it takes the show way too seriously. It's awesome to read what happened "next" - Kirsten Beyer definitely has the characters down.
