We'll - this is what I would do next if I were Kelsey.
I would go back to the United States and start getting my life back. Go to a different state with a false identity with the help of Mr. Kadams and go to college. I would leave on good terms and tell them she needed time to herself for at least 6 or 9 months before she would be ready to go on her next adventures with her Tigers. After finding out that Ren said "there is something off putting about her - I can't really describe it. It's just when I'm with her ....I can't wait to get away." I couldn't stay, knowing that I only make Ren unhappy by being there. It hurts both of them. I guess being older (38) I have learned not to push a relationship that is only felt on one side. If he remembered her - he could always come to get her to see if she wanted him back. As for Kishan - if he wanted, he could come with Kelsey to the United States and maybe be roommates and friends and she would let him know that she is grieving for Ren and she needed to get over him and for him to let her have that time. In the meantime Kishan and Kelsey could become closer as friends. When and if she got over Ren - take a look to see how she felt about Kishan. I wouldn't stay in India waiting for a man to realize that he loved me - it sounds like the odds are small that he will remember. At the end of the book I was hoping that when she got in her car - that she was driving to the airport to save her dignity.
