Crimson’s Dagger by Serena Simpson

Crimson spent her life outside the world watching it go by with critical eyes while refusing to interact with it. She never expected a male with a desire to sacrifice himself for others to catch her eyes. When he did, the last thing she could let him do was die on her watch.
Dagger had nothing to live for. If the choice were his death or his brother’s death, the one with a soul mate, he would die. Amid his grand gesture, a fiery female saved his life. Saving his life felt like a walk-through hell, but she got the job done.
Crimson let him go. She sent him back to his life while she stayed in her solitude. The ache she felt grew every day with him gone.
She sent him home, but he wanted to be where she was. He wasn’t handling his post-death life, well. When she showed up on his doorstep, he had no idea what was going to happen, but she wasn’t going to get away again.
She should be anywhere except on his doorstep. The life she thought was hers was spinning out of control. All she wanted was to be in his arms.
They might have thought it was a love made in heaven if there wasn’t an evil haunting the dream corridors. It has its eye on Crimson. The one female, Dagger refuses to give up.
