May I have you for an aunt? What a lovely thing to do!
“Inkheart”, a trilogy
A wonderful fantasy story about a 12-year-old girl who, with her dad, becomes entangled in a world of books. Basically, a love letter to reading – and gripping!
“Artemis Fowl”
Your nephew should like this one. Humour abound, and cool characters. The main character is a 12-year-old criminal mastermind, so… A boy’s book if ever I saw one. To fit the cliché, there are even guns involved – stun guns, though, nothing brutal.
“Molly Moon”
Quirky girl finds out she has hypnotic powers. Funny and gripping, though I did not like the last couple of the series.
“The Never-Ending Story”
Fantasy – a boy who gets turned into a hero. This is a book to curl up with, but probably not the right one for your nephew as there is not a lot of humour. If he likes fantasy, on the other hand…
“Narnia”
Wonderful stories, really painting pictures. If they haven’t read these, I’d include them for sure.
“The Exiles”
Hilarious book about four sisters who are all more or less nuts, but mean well. You can’t help but love them. Laugh-out-loud books, lovely to cheer yourself up with.
“Journey to the River Sea”
A story set in 1910, about an orphaned girl who gets sent to Brazil. Full of adventure, and superbly written.
For your nephew, how about a couple of “The Three Investigators”? I loved these! And, to add the humour that is missing in those, “Tales of a Fourth Grade Nothing” – one of five very funny books about a 12-year-old boy and his uniquely crazy little brother.
