It should have been so simple. So clear.
One at the top, three beneath him.
But nothing is clear anymore.
After two years living their lives together Alexander White has become distant and withdrawn, his mind a turmoil of unanswered questions, and the other three are broken because of it. Lost and left wanting. Well, two are. Lilah James doesn’t give a damn, other than ensuring Pascal Van Der Braack is adequately provided for. Unfortunately, he’s not being looked after at all, which means chaos and mischief could ensue at any given moment.
Always worrisome.
And when a rather royal problem comes to tarnish the already broken, something that none of them know how to deal with, whatever structure they had is suddenly unable to carry on.
Becoming a four in love brought its own battles.
Staying as four might break them all.
