I'm not sure this cover could scream "For fans of the Last Binding series" more loudly if it tried. Truth in advertising, though.
Also I couldn't tell if this book was trying to be Dickensian and just not actually succeeding or if the throwaway references to Dickens characters were one-offs. There's definitely something in the names that feels our old friend Charles, but not so much in the rest of the style. In the above ground plot themes, well, obviously.
This book takes more from Rosetti's "Goblin Market" (thank goodness) and is, overall, true to the story Rosetti tells of bargains made and narrowly avoided and the place of love and care in/against the power of the bargain.
What it doesn't do, that "Goblin Market" does, is transcend that world of give and take. I'm not sure it's trying to, but it may have been a book with much more to say if it had.
Not that I mind a book that is exactly what it says on the tin - what if we beat the villains at their own game?
