It's an allegory.

. . . and a pretty heavy-handed one. Don't know if I can finish the whole thing. This is the second one in as many weeks. At least the other one was short.
i actually started this one in January and kept interrupting it for things like life. Could be another reason why its not captivating me.
on the good side, there's a tree house.
“That’s a lovely banyan tree. We had them in Australia.” The massive beauty protruded from a hill overlooking the river. A large root, exposed at the river’s edge reached toward them like an inanimate tentacle. Thick horizontal branches extended from an open center.
She longed to climb its graceful branches. If they’d been on land, she would have made a beeline for it. “It would be perfect for a tree house if I was still into that sort of thing.” His puckered brow softened.
His grip on the paddle even seemed to loosen a bit. “You can never be too old for a tree house.” Anna hugged her knees. She was quite certain she would never be too old for one.
Oh, and it's time travel, which is why I selected it in the first place. We have a fifth century Mayan princess and two twentieth century children, a Washington state boy from the fifties and an Australian girl from the thirties, all transported to a timeless place, where the only inhabitants so far have been talking animals.
and we've had, like, a hundred pages of "rest and meditation," which is driving me more than a little nuts.
“Why are we here, great one?” Nik knelt in front of him always so formal like he was royalty instead of her. “What wisdom may I take to my people?”
“For the moment, you need only rest -- renew your minds -- just as you learned to do in the Place of Stillness. . .
“Isn’t it amazing?” Babana thrust his paws wide like a conductor calling an orchestra to attention. “We have a symphony of crickets under a cloudless, starry sky. You will come to enjoy this, I assure you.”
And Brendan, the boy, has been given a talisman by one of the denizens of the woods, and he's become all moody, unpleasant, argumentative, and solitary. Yawn.
(I'm only 26% in, it's too soon to quit yet.
But, it's taken me weeeeeks to get this far.
you can do it, you can do it.
probably I'll start loving it in the next ten pages! Okay, fifteen pages.
Here I go again.)
