If he had been with me is a book about a tragic teenage love story where two ex best friends who went from hating each other to loving each other. In the end they fall in love, but that only lasted so long before they were torn apart by death. The theme of this book is grief and it shows how broken Autumn was when she lost her love and how she tried to cope. If you liked the book The Way I Used to be I think you would enjoy this book as well.
