Okay, here comes the first logline request.  Just to recap - a  logline is a one-sentence summary of your story that consists of three major elements: the character, the character's goal and whatever stops them from reaching that goal (circumstances, antagonist etc). Ideally, a logline should list the stakes of your novel, the key conflict. 

Here is the original logline 

After their friend goes on a self destruction mode and dies on her own birthday, grief makes Kiara and Vicky look past their estranged relationship only to find that desire to be loved hinders the path to the killer, if not killers.

Feedback: 

In terms of logline requirements, this isn't bad. We have the character(s) Kiara and Vicky, they have a goal (actually two, they want to explore and, presumably, improve their relationship) and they want to find killers. 

However - there is quite a lot of unclarity here. 

The friend going into self-destruction mode and dying on her birthday implies self-harm to me. Next, I wonder how grief can trigger people into exploring relationships - the link, the motivation for their actions isn't clear. Then we have a desire to be loved, which is implied in their relation-ship explorations, so it sort of works, but then we suddenly get confronted with a killer. For me, that came totally out of the left field. 

Stylistically, there also are a few issues, but those we can fix when we have a reworked logline. Now, since we have that killer element at the end, I can only presume that the friend dies of unnatural reasons i.e. is murdered. that assumption is key, otherwise the logline makes no sense (i.e. no link between the death and looking for a killer). I'm not sure we need the birthday bit here. It won't do any harm, but it lengthens your logline and therefore has to be relevant to the plot to be mentioned. "Grief makes Kiara and Vicky look..." is a bit of a clunky construction, plus we have a logical issue here - it's not the grief that finds out about the desire to be loved. So that needs to be reworked. "path to the killer, if not killers" for me is not only confusing and oddly phrased, it also reveals what might well be a plot twist. You don't want that. 

With those points in mind, I gave it a bash. 

Reworked logline 

When their mutual friend is murdered (dies a horrid death on her birthday would be a slightly longer version), shock and grief forces Kiara and Vicky back together. But they soon realise that a craving for love won't help them find a killer. 

@storiesunfolded_xo  This is the vibes and core of your story I get when reading your logline. If this is NOT what you had in mind, send me a PM, since that would mean the logline has an issue in terms of the key message it conveys.
