Heather thought she'd finally figured her sexuality out, but there's so much more to learn. Kyle hasn't dealt with his past, and it's long-past time he faced his most visceral of fears. Marcus has wanted his own slave — someone to love and adore and hurt — for most of his adult life. How much negotiating is he willing to do to bring the woman of his dreams under his roof? If she balks at too much of what he wants, is she really the one he's been searching for?

Going from a threesome to a foursome is a much bigger deal than it would seem at first glance. One would think the fourth person being a slave under a near-total power exchange would make things easier, and it does in some respects, but it also complicates life in unexpected ways.

You'll want to strap in and charge your batteries for the second half of the Safeword: Mayday duet, because this one goes to a whole mountain of unexpected places.
