From Goodreads - A teen’s luxurious weekend birthday party is taken hostage, and she flees to the hidden tunnels in her family’s mansion while the rest of her friends, including her former BFF, are trapped in the living room, and soon the teens on both sides of the wall find themselves fighting for their lives.
Sera is dreading the evening – attending the birthday party of her former best friend, Ariel. Her father is demanding she go, as he and Ariel’s father are business partners. Ariel hasn't spoken to Sera in months, and in doing so, most of her friends and classmates give Sera the cold shoulder. She doesn't feel she did anything wrong, but Ariel believes she did and now hates her.
The girls and their friends all come from wealthy families, so famous rock star singer Hudson Winters has been hired to sing at Ariel’s birthday party. Sera adores his music, so she’s looking forward to that. When the lights are turned down low for Hudson to sing, shots ring out. Not only is Ariel’s father shot, but so is a student. But Ariel has disappeared and only Sera knows where she could possibly be.
Hudson and she form a fast friendship and try and outwit the terrorists. But the classmates quickly inform them that if anyone can help them find Ariel, it would be Sera. Now, if she doesn't tell them in the next hour, they’ll start killing more kids.
The Girl in the Wall is a quick-paced read with great characters and a plot that twists and turns. I didn't figure out who was behind the attack until almost the big reveal as it could have been several people. Ariel and Sera were well-developed characters, as well as Hudson, even though I would have liked to have seen more of the supporting cast have more of a back-story All in all, a quick, entertaining read!
