Adaptation by Malinda LoRead about another entry on the list.
In this YA science fiction novel, the protagonist Reese Holloway and her partner David are driving home to San Francisco when they get into a car crash with a bird in the Arizona-Nevada desert that is Area 51. Holloway wakes up in a military hospital about a month later, healed from an operation. It isn’t until Holloway gets back home and encounters Amber Gray, that she realizes things are wrong and she may be wrapped up in one big government-extraterrestrial conspiracy. Moreso Area 51 adjacent as opposed to centralized, Adaptation is actually a two-part novel followed up by Inheritance.
