A/N: The frame for this story can be found in Chapters 7 and 8 of "D'You Wanna Come With Me?" - the gist of it is that the Doctor accidentally took Harry, Ron and Hermione to Temeraire's world, where Harry managed, with his usual flair, to bond a hatchling dragon whom he called Fortuna; in an effort towards damage control, the Doctor went looking for a device able to reduce Fortuna's size, leaving the three wizards there in the meanwhile, but instead of returning after ten minutes, he showed up ten months later. This story deals with those ten months.
It takes a while for things to get sorted out somewhat acceptably.
First there is the uproar over the 'witchcraft' that has disappeared the mysterious blue box and the two suspicious people that had gone in it. Hermione hears very little of this over the pounding of her own heart and the screams of fury and panic that she vents, unable to believe that – that – alien – has left them here.
It's Harry and Ron who have to talk fast and climb mirrors and eventually manage to convince their 'hosts' that a) they're not French spies (their decidedly British accent helps a lot with this), b) they are not dragon-thieves and had, in fact, not meant to steal a dragon at all and c) they really kind of need help, if they wouldn't mind, thank you very much.
Then there is discussion about accommodations and jobs and whether or not they can stay at the Covert, discreet bits of magic to provide identifications letters here and bank credit there (good thing Hermione had researched these kind of spells extensively in preparation for their year on the run), the tentative efforts of the dimension travellers to figure out at least the basics of the world they've stumbled into.
And the continuous tension of being alert because the Doctor could come back any time – literally any time – and they have to be ready, they can't miss their chance, what if he abandons them again?
Hermione has a full tirade worked out before the end of the second night and can't wait to yell it at him; she keeps perfecting it day after day.
Even after they've settled into more or less acceptable lives, (Harry and Ron and the growing Fortuna almost seeming at peace with their unexpected situation), Hermione continues to collapse on the bed she's been assigned, at night, and let the shock accumulated over the day overtake her.
She is in a different world, a startling, fascinating one where sentient (and, in fact, quite intelligent) dragons live and work side by side with humans!
This isn't bad per se, it might even be fantastic, except for the fact that they're trapped here, because that absurd alien has left them.
Oh, and Harry has a dragon.
But that's really just Harry's luck and it isn't remotely as much a problem as the fact that they have no way home. And no library to research one. And no option to practice their magic. She'd loved to explore the wizarding world and she would love to explore this world as well, if she didn't feel so trapped here.
She is in a different time, on top of everything, and this is harder to cope with than the dragons, surprisingly.
She should sort of be used to it – the wizarding world is certainly behind the times when it comes to technology – but then again, magic eliminates the need for a lot of said technology. And Hermione has never before lived without indoor plumbing, nor did she ever want to.
As for finding herself a place in this society, there doesn't seem to be one she can be comfortable with.
She's vaguely relieved that she isn't expected to stay indoor and spend her time embroidering, at least, but things are a long way from what she's used to. If she has to deal with many more condescending males looking surprised she can even read, let alone interpret charts or do the budgeting and ledger maintenance better than the lot of them combined, she might just go spare.
Even the female aviators tend to dismiss her – apparently, if you weren't raised in the Corps, then you must be an empty-headed wilting flower for sure.
She ends up spending more time with the dragons than with the humans: at least they provide intelligent conversation. In fact, most of them are eager to discuss anything from poetry to current events and have excellent heads for maths!
On top of everything there is the niggling fear: what if the Doctor doesn't come back for them? How will they get back home? How will they cope if they're stuck here? How will they even survive? How – how – how?
The passing of weeks does little to change this nightly mantra.
