Tommy Black and the Staff of Light

For fourteen-year-old Tommy Black, nothing is worse than being raised by an overprotective grandfather in the city that never sleeps. That is until his grandfather is captured by magical creatures and Tommy has to save him with his family's magical staff. That wouldn't be so bad, but the only magic he can do with the staff is weak -- making light. What the heck can you do with light? Tommy finds out as he fights golems, shadow creatures, and djinn in a journey that features a magical river, an enchanted train, and an illusionary fortress. But the worst part of all? Tommy has to save his grandfather with the help of Naomi, a girl whose talent with magic is only rivaled by her ability to hurl insults.
