Due to the lack of time I have had to complete the actual book in time for the third advent competition, the remaining chapters in the middle will remain a mystery as of now; however, I will reveal the last few chapters and the two alternate endings that are there. You may feel free to read the wrap-up below if you wish to know how it ends (or how it is planned to end at this moment).
As you approach the ending, it is finally spring time in Canlagos and the reader comes to learn that Angel and Ben have become very close (these are primarily what the middle chapters are aimed at to build for the ending). In a quick series of events and at the last few chapters before the alternative endings take place, Angel has a vision that she was sent to earth to kill Ben. She also learns that she was also the death angel who killed Isabella and was also the same Rosangela who fell in love with Raguel years back- hence why Rosangela disappeared because her work was finished.
In addition to all of this, Raguel then comes to her room knowing that she had this vision and reveals to Angel that he too is a death angel and they were paired up to kill Isabella together. However, their distraction in love with each other led the two to become distanced from each other by God's command. So when Angel was received back in heaven, Raguel was left on earth as punishment. Later though, Raguel redeems himself and becomes Angel's supervisor to ensure that she does the job right and guides her. He tells her, "there are bigger plans for the future." The dagger gifted by John in the early chapters is quite symbolic here as well, but John's true self still remains a mystery to the whole town including Raguel.
So now after learning all of this, the reader is forced to make a decision. Is she to believe that she was a death angel sent to murder Ben, her new lover, or does she continue to love Ben without murdering him in spite of the overwhelming amount of evidence she just learned?
Angel decides, from a gift of free will as granted by God, that she will continue loving Ben as it's too good to be true. She comes to the conclusion that the pastor of Canlagos is mentally insane and goes to their (Ben's and Angel's) previously planned picnic that was made yesterday. As the two have their picnic together, they talk with each other as they had done before for so long. Though, Angel can't help her consciousness getting in the way and tells Ben that she needs time alone for a bit. He agrees and says he will just wait for her to come back. Two hours pass and a storm approaches. Suddenly a bolt of lightning strikes from the top of a hill. Angel's last sight is Ben caressing her in his arms.
The epilogue stays true to the point of view that the story has been told the whole time and Angel finds herself in heaven before God. God tells her that she has blatantly disregarded His orders and is now responsible for another one's head. At hearing this, Angel is quite confused; she accepts that she is a death angel, but how could she be responsible for another? It is then revealed to her than Ben has ended up in Hell due to her lack of obedience. God tells her that the only way to save Ben's soul from Hell was to murder him- then and only then would he have come to believe in a greater power; however this is not so when Angel decided to love him. She looks down to Ben and speaks a series of final words which ends the book, but she knows deep down that anything she tells him will never be heard. He writhes in pain and burns in Hell for eternity.
The only possible alternative is that Angel accepts that she is the death angel and must kill Ben as she was ordered to. So they once again go on their (Angel's and Ben's) previously planned picnic that was made yesterday. Angel is different this time though, she knows deep down that she will need to kill Ben here where no one else will see her; if she does so then the risk of other souls are at stake. Though this time, Ben realizes he forgot a knife and must go back to Canlagos quick to get one. Angel asks him if he can bring her dagger instead which she received from John; Ben agrees. At returning Ben hands her the dagger and quickly she tells him she's sorry and stabs him in the heart. She sings a song in Hebrew as he fades away, and after his heart has stopped beating she goes to the woods where she started out in the first place. She climbs to the top of the tree and falls asleep as she cries wondering if she has done the right thing.
Angel now finds herself in heaven before God... and Raguel. God tells her she has done well and hints to her that He was John to further help guide her- though never outright stating it. Raguel then tells her that someone would like to meet her. She is led to Ben, and the two converse. He feels no regret or pain by what she did; however, Ben does say that the two could never love each other. Angel is shaken by his confession, but she too knows that it would never have worked out unless... she wonders what would have happened if she continued loving him on earth. Would her rights as a death angel have been revoked, and the two could have lived happily together?
