I love how Achsah's plan to send her parents a message from her through the ages revolved around multiple factors.
1.) She remembering the layout of her parents house and the surrounding area correctly. (It's not much the layout that's the potential problem as locating the correct place must've been. 350+ years is a long time! Surely the geography and plant community changed quite a bit in the intervening centuries.)
2.) Caleb deciding to dig a root cellar like he always talking about doing. (Didn't happen, but luckily Ghost decided to dig in the exact same spot where she buried the puzzle box anyway.)
3.) Burying the message deep enough for it to not be found right away, but not so deeply that it's unlikely to never be found. (Image Caleb and Evelyn coming across the message... while building the house! They'd never let Achsah out of their sight!)
Oh, yeah, it was a shot in the dark, for sure. She buried that thing with NO idea if it would actually reach them.
In terms of part one, the house IS close enough to an unchanging landmark (the third rib) that she could probably get pretty close. We'll say she used oracle magic to predict the changing landscape, or she had a photograph of her house that she took from the third rib to guide her, or even that there's actually a couple dozen boxes buried in the surrounding area with a copy of the letter and a bracelet, lol. They can go find the rest of the boxes and EVERYONE can get an Achsah bracelet.
They got really lucky with Ghost finding the box, for sure, but in terms of how deep she needed to bury it, root cellars have to be a certain depth to really work properly, so if she buried it with the thought that Caleb would find it when he dug a root cellar, she could just bury it at that depth, and she'd be set!
But overall? Yeah. It was a desperate last attempt. It's a little sad to think about her writing a letter that might never reach its recipient, with no way of finding out if it got that far, and just hoping that fate would be kind, and her parents would find it. But, hey, it worked!
