Dracon Rouge

When her sailboat is chased by Chinese pirates into the Japanese equivalent of the Bermuda Triangle, American volcanologist, Gem Ishiwara, puts up a good fight. Good but hopeless, until she is rescued by what her eyes tell her are red dragons, and her brain tells her is an impossibility.

Her brain wins with an expedient Ctrl/Alt/Delete. She wakes to discover aliens really are on earth, they've been here for far longer than anyone ever imagined, and they are very, very interested in her.
