There is no information available to me about a love story between Rashi Khanna and Naman Mishra. It could be that they are just colleagues or friends and there is no such romantic relationship at all.
I'm not sure who Jodi Hildebrandt specifically is. There could be many people with this name. Maybe she is an ordinary individual with a personal story that is not widely known, or she could be known in a specific local context, community or field that I'm not familiar with.
One of the best Jodi Picoult novels is 'My Sister's Keeper'. It tells a heart - wrenching story about a girl who was conceived to be a donor for her sick sister. The ethical and moral dilemmas presented in the book are extremely thought - provoking.
