A classic series kids around the world have grown up reading is The Chronicles of Narnia. While Narnia is very clearly a Christian allegory, it can be enjoyed without reading too deep into the Christian subtext. The writing is great and it's a great magical adventure for both kids and adults.
You should also read Garth Nix's newest series, Keys to the Kingdom . It's also a great read, both for the kiddies and adults, one of the better series for kids.
Don't forget to read Jonathan Stroud's very impressive The Bartimaeus Trilogy It's an action-packed thrill ride about a magician's apprentice who manages to summon a powerful genie (Bartimaeus). Bartimaeus is less than pleased with this turn of events and tries to sabotage his young master at every opportunity. Hilariously funny, at times very dark, with great writing, a great cast of well-developed characters, and an interesting world, Bartimaeus is a must read series (for both kids and adults).
And finally, Harry Potter . I won't bother explaining why.
