Relativity by Antonia Hayes

This story is told mostly by 12 year old Ethan, who is fascinated by science and is bullied at school because of that.  His mother, Claire also tells parts of the story and his father, Mark, who Ethan had never met because Mark left when Ethan was 4 months old, also tells part of the story.  I enjoyed the science in the book. When Ethan finds out that his parents have been in contact with one another he is determined to meet his father. The story was sadder than I thought it would be.  It is well written and captivating and I highly recommend it.
