Holding Up The Universe by Jennifer Niven

Jack suffers with prosopagnosia and was dating Caroline until he kissed her cousin having thought she was Caroline. His dad had cancer and cheated on his mum with his science teacher which causes him a lot of stress still.

Libby was 600 pounds but is now 300 and can leave her house her mum died and she put on weight. She tried to leave her house before but had panic attacks but is more confident now she's lost some of the weight.

Libby and Jack are involved in a minor incident in the cafeteria of their school which results in them both landing school community service after the end of the school day together.
They both remember her house being half destroyed to get her out to hospital when she had a bad attack, they soon realize they knew each other before now as Jack had always lived opposite Libby, knew her story and didn't judge her then and doesn't now.

Libby also loves to dance and the school team, Camels host team try outs where Jayvee and bailey cheer her on to get through trying.

I really enjoyed the book overall, I liked how Libby was strong willed and didn't take no messing from anyone but stood up to them and faced things herself unlike so many book characters where boys are needed to save them. The sense of girl power friendship between the three girls was also a nice touch that they reconnected and didn't judge Libby.
