The Bitter Twins is the second instalment of Jen Williams’ Winnowing Flame Trilogy and is an excellent second in series that demonstrates William’s ability to create a richly woven world, full of history and religion and characters that are a delight to read and fall in love with. Before reviewing The Bitter Twins I would point out that it is necessary to read the Ninth Rain first.  The story picks up immediately after the conclusion of No.1 and there is no recap of previous events so if you haven’t read the first book then I strongly recommend you stop right here, don’t read this review, simply go and pick up the first book.  The other thing that I would mention is that this is a book that is a little difficult to review without giving away spoilers for the first book or indeed for the content of The Bitter Twins so I’m really going to avoid discussion of the plot and limit my review to the writing, characters and world building. Once again the story brings our favourite characters to the table.  Lady Vincenza, or Vintage, again plays a key role.  Not to be deterred by her lack of either…
