I like the way you introduce the stars in your stories. I never thought about why the sky was blue during the day and dark at night, but everything is influenced by the sunlight, the way you write as you add science with fiction because for dreams are other dimensions, many appeal to metaphysics and astral travel. Your story was captivating, even though it is long it manages to catch you enough to finish it and that, only those people with a majestic writing, like yours, can do it.
For me the one who suffered the most in this story was Tom's sister, deciding between her brother's life or her best friend, that must have been hard for her, not to mention the time she spent taking care of her mother, it must have broken her heart not being able to hear her mother say a word to her, her life was normal a majestic doctor, but sometimes life takes you out of your comfort zone, the way she faced things is wonderful. You motivated me @nestorvc01, your story has changed my way of thinking. Thank you.
