The Last Day of Forever by Maggie Braun

Soul mates reunite at end times to finally heal the divisions that were created in lives past. They meet at a time where the world is on the brink of extinction and only their perfected love can save the planet. They are followed by other worldly Beings, as Pleaidians, who intercede to help their mission to overcome their transgressions and learn to forgive, adding the love they share to shift the world from evil to peace.
