Penelope Crumb Follows Her Nose [EPUB ebook] 
Book 1

Some interesting facts about Penelope Crumb… She has: A brother so awful he MUST be an alien. A mum who draws body parts (ewww!). Her grandpa’s nose … but no grandpa. Her family haven’t seen him since her dad died. So Penelope and her friend Lizzie Maple set off across town to find Grandpa Felix, skipping school, taking trains and calling every F. Crumb in the phone book. But what if Grandpa Felix doesn’t want to be found? One last fact about Penelope: she doesn’t take no for an answer.
