Lisa Lutz - The Spellmans Series [Book 1-6]

The Spellman Files
Meet Isabel "Izzy" Spellman, private investigator. This twenty-eight-year-old may have a checkered past littered with romantic mistakes, excessive drinking, and creative vandalism; she may be addicted to Get Smart reruns and prefer entering homes through windows rather than doors -- but the upshot is she's good at her job as a licensed private investigator with her family's firm, Spellman Investigations. Invading people's privacy comes naturally to Izzy. In fact, it comes naturally to all the Spellmans. If only they could leave their work at the office. To be a Spellman is to snoop on a Spellman; tail a Spellman; dig up dirt on, blackmail, and wiretap a Spellman.

Curse of the Spellmans
The Spellman family's adventures continue in CURSE OF THE SPELLMANS. Isabel Spellman is back and she's just been sprung from jail for the fourth time in three months. When she finds herself homeless and simultaneously barred from the Spellman offices-cum-residence by a very inconvenient temporary restraining order, Izzy meets with Mort Schilling, her octogenarian lawyer, to hammer out a defense and save her now endangered P. I. license. Over San Francisco's best New York-style deli fare, Izzy recaps the highlights of her recent past and her encounters with the man whose villainy she's determined to unveil—even if she must break the law to do it.

Revenge of the Spellmans
Private investigator Izzy Spellman is back on the case and back on the couch—in court–ordered therapy after getting a little too close to her previous subject. Her newest client is a husband worried that his wife is cheating on him—a seemingly open–and–shut case that won't quite stay shut. When it finally explodes, the fallout reaches the highest levels of city politics. And takes Izzy into uncharted territory. Meanwhile, her brother, David, the family's most upright member, has left the country—and maybe his senses. When her wayward sister Rae aces her SATs, no one knows if it's just another scam. Even Izzy's mom might be running a con. Add to the mix a pair of mysterious women who don't quite seem themselves, a local PI out for revenge, and a car that never stays where Isabel parks it.

The Spellmans Strike Again
At the ripe old age of 32, former wild child Isabel "Izzy" Spellman has finally agreed to take over the family business. Let's just say the transition won't be a smooth one. Her first priorities as head of Spellman Investigations are to dig up some dirt on the competition—slippery ex-cop Rick Harkey—and to track down a stolen screenplay called The Snowball Effect. Next, faced with a baffling missing-persons case at the home of an aging millionaire, Izzy hires an actor friend to infiltrate the mansion as an undercover butler. Only he enjoys the role a little too much.

Trail of the Spellmans
For the first time in Spellman history, Isabel Spellman, PI, might be the most normal member of her family. Mom has taken on an outrageous assortment of extracurricular activities—with no apparent motive. Dad has a secret. Izzy's brother and sister are at war—for no apparent reason. And her niece keeps saying "banana" even though she hates bananas.

The Last Word
Izzy's troubles are just beginning. After her hostile takeover of Spellman Investigations, Izzy's parents simply go on strike. Her sister, Rae, comes back into the family business with questionable motivations. Her other employees seem to be coping with anxiety disorders, and she has no idea how to pay the bills. However, her worst threat comes from someone who is no relation.
