Keep Me Breathing - The Infernal Cave, #1

WHAT DO YOU DO WHEN EVERYTHING AROUND YOU FALLS APART? Their mission was supposed to be simple: Go to Lucif. Find out who owns the chain. Go back home. Find him! Reopening old wounds was not on the list. Neither was letting secrets be known or catching feelings of the wrong kind. On the outside Fubuki Snow is alone and her personality is less than friendly. She barely leaves her house and her only friend is considered family.
But she has everything she needs. Hobbies, work and a family she loves dearly. She doesn't need romance, adventure or shallow relationships. No matter how much her best friend pesters her about it. Sakura Petal might be considered the opposite of her best friend. She's outgoing, adventurous and spreads happiness wherever she goes. She has everything. Unless you ask her. Then she's the reason her best friend is alone and she's a horrible mother. When Sakura's son disappears, the girls must not only venture into the cave system to find him.
They also have to face their own insecurities and past mistakes.
