The first book (
Leviathan Wakes) isn't available until sometime in June, I think, but The Expanse series by James S.A. Cory (aka Daniel Abraham and Ty Franck) is purported to be
unapologetic, old-school space opera.
Abraham claims that each individual installment will wrap-up the majority of "loose ends" (since they don't know how long the series will run).
I know it sounds like my cup of tea... especially in this day and age where the releasing of one-fifth (and less) of a book at a time seems to be all the rage.
