Ravel promises the help she needs - but or a heavy price.

But it's a sin for a warden to feed a vespertine- let alone love one. As Everline and Ravel travel across the desolate moorland, their fractured, temporary, trust in each other is put thrillingly to the test and Everline realises the question isn't only whether she will survive the journey - but if she does, if she will ever be the same again . . .
