Who Do I Talk To? by Neta Jackson.

i have read some of Neta Jackson's books before and I heartily enjoyed them. That's why I picked up this book with a sense of glee... Neta Jacson also wrote the Yada Yada Prayer Group series (I highly recommend) and this book has some continuity to that series.

Gabrielle Fairbanks is going through a divorce with her husband. He has taken her two sons, Paul and P.J. and gone to his parents. He shut down her credit cards and changed the locks on their penthouse. Needless to say, Gabby is not happy, and is out on the street with her elderly mother, known affectionately as "Grandma Shep."
Gabby works at a place called Manna House, which is a refuge for women coming off the street. Gabby finds herself now living where she works... Still trying to sort out her divorce and regain custody of her children, Gabby sees a lawyer named Lee Boyer and he helps her go through the legal process of trying to drain her husband for all he's got. If she gets money she can get an apartment to get custody of her boys. Boyer takes more than a legal interest in her and Gabby likewise to him...
Around the middle of the book, Gabby's mother, "Grandma Shep" dies and Gabby transports the body back to her hometown to have a funeral. Gabby travels with Manna House volunteer Jodi Baxter (from Yada Yada books) and Lucy, a bag lady who befriended her mother and her dog Dandy. Gabby and her sisters prepare the funeral and it proceeds without a hitch. After, the will is read and each of the sisters inherit 250000 dollars. Gabby is ecstatic, now she can get her kids back and rent the magnificent apartment she'd been looking at.
The book ends with much more to come...

Also, something to look forward to...I will be reading Gulliver's Travels and will either be posting later this year or by the chapter:)
