I picked this up expecting it to be similar to, or at least springboard from The Man from Atlantis, however other than the title there's not much connection, and instead this is a rather light sci-fi romance.
Our heroine Jenna is an archaeologist looking for artefacts in the desert, (on her own!?). She finds a stasis chamber and trips over activating the controls awaking Kynan. Kynan is an Atlantean, the advanced human society who inhabited the Earth before the flood. A few of them either fled the Earth or put themselves into space ships and headed for the stars to avoid an imminent meteor strike. Knowing that the military would no doubt want to dissect him or force him to make advanced weapons, she decided to take him home with her instead to get him acclimatised to the times. Kynan spends most of the novel trying to make a transmitter to contact the Atlanteans in space. Jenna helps him and the pair fall in love. Their happily ever after is impeded by 1) A suspicious army Colonel who thinks they are drug smugglers, and 2) the fact that if Kynan does manage to make contact he will go home and leave her.
This is very 'wish fulfilment' fluff. Kynan is pretty cardboard: a perfect drop dead gorgeous hunk, he's kind and values Jenna for her intelligent mind. Jenna is supposed to be a super intelligent archaeologist, but other than being told this repeatedly I am far from convinced (she's like the Ally McBeal of lawyers) - She spends most of her time drooling over Kynan and does nothing sensible or intelligent in the whole novel other than give a couple of literary quotes. She never comes up with any plans, do anything technical, or even question anything. She's digging in the desert, alone. Finds a strange man and takes him home with her. Eh?
This also wastes the whole concept of Atlantis. There's no aquatic connection and he could just as easily have been a martian.
So this one really is a bit of romantic fluff. It's fun and readable, but very shallow on character and emotion.
