The phantom agency and the case of the missing souls

Destiny is not your ordinary girl.
Besides the fact that she straggles two world’s.
She is also the spirit the powers that be have been waiting for.
That’s right.
Destiny is a spirit. Not born on this plane of existence.
She hails from beyond the veil. Where a soul goes when the vessel can no longer hold it.
Spirits like Destiny are called shadow agents.
A shadow agent hunts down and returns the souls that flee back to the mortal side of the veil. Where these souls start to cause trouble.
The Powers that be have sensed uneasiness for a while now and need Destiny to accept. Well. Her destiny.
All Destiny will have to aid her in her task is a sassy best friend and a talking, scruffy white cat.
Destiny will need all her skills, all her courage and wits if she is going to prevail and bring the missing souls home.
