Hexes and Wolves by Rhiannon Lee

Four swords to fight by your side, tried and true and in the breath of time.
One through hope, one through pain, one through grief and one through gain.
Hands clasped under the moon, the three fates shall repair the loom.
Like greeting an old friend, if that friend is a slap across the face from reality, Lucy launches herself headfirst into a new series of challenges that come with the territory of being the Queen of Hell. After finding herself caught in the middle of an ongoing conflict simmering just below the surface of Hell’s five realms, Lucy must contend with a growing list of the dos and don’ts of ruling while making sure she comes out unscathed.
On top of being pulled every which way by royal duties and rules, Lucy must also juggle a newfound romantic life she couldn’t have previously imagined. As her love for Cain grows, the arrival of a mysterious stranger throws a wrench in her initial plans. And of course, he’s not the only one who has their eyes set on the vivacious queen.
As if things couldn’t get any harder, the uncertainty of Lucy’s future increases as a lurking threat begins to rear its head. Before long, she is faced with the decision about how to protect herself, those she loves, and a kingdom that has not only grown on her, but depends on her birthright to keep it in balance. Can Lucy figure out the key to keeping her world intact while also opening her heart to the love of all the men in her life before it’s too late?
