The Shortcoming by Shay Savage

As the bond between Alexandra and Branford deepens, they each have their hopes for the future. Branford aspires to lead his kingdom with both wisdom and a firm hand while Alexandra fervently wishes to give her husband an heir. As Alexandra learns to embrace her noble role, she finds friendship with the girl she rescued from an abusive owner. It seems as though their lives have finally rewarded them with the happiness they have sought.

But happiness comes at a price, for war is on the horizon.

The neighboring kingdom of Hadebrand has amassed an army, and against insurmountable odds, Branford must lead the fight for his people. Alexandra is terrified but cannot let her fear show for she must serve as an example to their kingdom.
The war must eventually end, but there is only one thing on Branford’s mind—to continue the royal lineage. But how will Alexandra overcome her heartache when she can’t give her husband the one thing he must have?
