Mills and Boon Intrigue
Mills & Boon®, the Harlequin branch in the UK, started the Intrigue imprint in July 1994, reissuing titles from the Harlequin Intrigue imprint as Silhouette Intrigue.
From May 1995 on titles from the Silhouette Shadows, Silhouette Intimate Moments and Harlequin American Romance were included in the Silhouette Intrigue series. The books kept their ISBN, which makes it rather difficult to distinguish between the editions. (Since the UK-Edition is later than the North American, Amazon.com and its affiliates usually show the UK cover under the ISBN [1] and has to depend on customers to supply the original cover.)
When Mills & Boon® renovated it's Silhouette imprints in March 2007 their edition of Silhouette Intimate Moments, Harlequin American Romance and Silhouette Bombshell titles, called Sensation, and their Silhouette Intrigue merged into the Mills & Boon Intrigue imprint to from one super-charged, breathtaking romantic suspense series.
