1637. No peace beyond the line
(Book)

"It's 1637 in the Caribbean. Up-timer from 20th-century America Commander Eddie Cantrell and his ally and friend Admiral Martin Tromp start it off with some nasty surprises for Spain, whose centuries-long exploitation and rapine of the New World has run unchecked. Until now. If they want a fighting chance against the global superpower, new friendships must be forged with the native peoples. It is the up-timers who will not only shape the colonists' future in the Caribbean, but will also decide whether the colonists will be given access to a Louisiana oilfield that could change the balance of power. But Imperial Spain is determined to possess the new black gold of the Americas- in the form of crude oil pouring out of the Allies' pumps on Trinidad. The battle for the New World has begun, and it is a fight to the finish!"--book jacket.
