Let me start by saying, this book sinks its teeth into you from the very first page! As someone who's read countless paranormal books for tweens, 'This Totally Bites' stands out with its perfect blend of mystery and age-appropriate spookiness.

The main character Emma-Rose is so relatable - that awkward phase where you feel different from everyone else? Been there! Her pale skin, black hair, and aversion to sunshine had me chuckling at how seriously she takes her 'vampire' identity. The writing makes you feel every bit of her confusion and excitement.

When Great-aunt Margo arrives, oh boy does the fun begin! I found myself playing detective right alongside Emma-Rose, trying to piece together the strange occurrences. That scene with the animals in the park? Chilling in just the right way for young readers - enough to give goosebumps but not nightmares.

What surprised me most was how emotionally invested I became. The friendship struggles felt real, and that plot twist about Emma-Rose's true nature? Didn't see that coming! My 10-year-old niece (who I tested this book on) literally gasped out loud at that part.

The pacing is perfect - short chapters that keep reluctant readers engaged, with suspense building steadily. I caught my niece reading under her blanket with a flashlight way past bedtime because she 'had to know what happens next.'

My only minor critique? Some vampire lore purists might want more traditional mythology, but for the target age group (8-12), it strikes the right balance between familiar tropes and fresh twists.

Final verdict: Whether your tween is into paranormal stories or just needs an engaging read, this book delivers. It's like 'Cupcake Diaries' got a supernatural makeover - sweet with just the right amount of bite!
