I adore Marriage of Convenience tropes. Love all that forced proxmity with a stranger you have to build a life with....yeah... so gooood.

One of my very favorite sub tropes is Save From The Noose Marriage of Convenience. This is a plot where the hero or heroine is about to be hung or imprisoned for a very long time and gets out of it by marrrying. Yep. Love it. 

Can't seem to find out if this was actually ever a law but in Romanceland it is and my guess is there is some truth to the practice. 

Here are some wonderful Romances with this Theme. 

1. Shanna by Kathleen E. Woodiwiss

A pact is sealed in secret behind the foreboding walls of Newgate Prison. In return for a night of unparalleled pleasure, a dashing condemned criminal consents to wed a beautiful heiress, thereby rescuing her with his name from an impending and abhorred arranged union. But in the fading echoes of hollow wedding vows, a solemn promise is broken, as a sensuous free spirit takes flight to a lush Caribbean paradise, abandoning the stranger she married to face the gallows unfulfilled.

But Ruark Beauchamp's destiny is now eternally intertwined with that of the tempestuous, intoxicating Shanna. He will be free . . . and he will find her. For no iron ever forged can imprison his resolute passion. And no hangman's noose will deny Ruark the ecstasy that is rightfully his. 

2. The Texan's Wager by Jodi Thomas

8. Shadow's Stand by Sarah McCarty

Shadow Ochoa is lying low in the western Kansas Territory, waiting for his fellow Texas Rangers—the Hell's Eight brotherhood—to clear his name. That is, until he's unjustly strung up for horse thieving…and pretty Fei Yen intervenes. Invoking a seldom-used law, the exotic lady prospector claims Shadow as her husband and rides off with the bridegroom shackled to her buckboard.

Savvy, fearless Fei is single-mindedly devoted to her hidden claim and all it promises: wealth, security and freedom. A husband is just a necessary inconvenience and a name on paper to hold the claim she cannot.

Shadow isn't a man to take orders from anyone, especially from lovely Fei—except that the daily friction between them ignites into nightly blazes of all-consuming passion. Soon Shadow is dreaming a little himself: of the life they could have if only Fei could see past the lure of independence. If only bounty hunters weren't closing in on him. If only he's left standing when the impending showdown has ended….

With the line between England and Scotland shifting daily, the Earl of Douglas wants to win back every inch of Scotland that the English have claimed; whereas the equally powerful English Percies (under Hotspur) want to win back the land between Northumberland and Edinburgh; and the Murray family is caught in the middle, shifting its alliances to try to survive. Uncertain whether she is English or Scottish and abruptly married to Sir William who is staunchly loyal to the cause of Scottish independence but who also has promised he'll never take up arms against her family, Meg Murray learns two things: first, Will's word is his bond; second, her favorite brother is spying on Douglas for Hotspur. As Sir Will faces the dilemma of honoring his word to the unscrupulous Murray without betraying Douglas, Meg must choose between betraying the husband with whom she is rapidly falling in love, or betraying her own family and best-loved brother.
