In the past, I have read many wonderful biographies. As a child, I read Amar Chitra Katha and then as I grew my mother encouraged me reading Puran. I also read Geeta press "Bhagwat Geeta" in Sanskrit to understand better (since the Hindi translation does not reflect true meaning).
Reading Deep Trivedi's "I am Krishna - vol.1" has been a transformational experience. Seeing the human dimension of Almighty after reading Puran Katha and Bhagwat Geeta was a psychologically insightful, helping to look for a searchlight. Must buy other two volumes and I am Geeta. Meaning of "I" in this book is quite mystifying.
