Intense cliffhanger! So far, I really like this story (also all the plant names for the characters were nice) Cardamon's really cool, and so is Bergamot (he's funny.)
I would suggest that character dialogue should be on their own line. 

EX:
"You two newlyweds got lost?" [...] 

"Yes, we are lost," Cardamon says.

Having all the characters' dialogue made it a little harder to read, that's all. Sometimes the tense switches from past tense to present tense. (EX: "I tear my gaze away from the brooch, meeting Cardamon's cross face. She cocked her head to the stairs, and I nod.) I would suggest keeping it consistent. 

Last, this is a minor one - character dialogue that follows with 'he/she said' or something like that should end with a comma before a quotation mark. 
EX: "We should go to sleep while it's still dark Cardamon," I whispered.

 But that's really all, and they're minor errors. Overall, this story's really great and I'll definitely be reading more of it! Keep writing, Toast.org!
