I can connect Evyn from Bounce by Natasha Friend and Sam from Lush by Natasha Friend. In both books the main characters have similar problems. Evyn has to deal with a new family. Sam has to deal with her dad being an alcoholic and when her dad went to this alcoholic place and it seemed like she had to deal with a new family. Evyn has to cope with her dad (Birdie) has married a woman and she has a big family so Evyn has to cope with a new family. That is how Sam from Lush  and Evyn from Bounce have similar problems.
