when you get a book and hate it.

ok here is a doozy of a deal, when you hear about how great a book is and you can't wait to read it and it is a total absolute fail. what do you do??? stick it out read it to add to you number of read books on good reads? do you give up and move on? come back to it later? I have had this happening more and more since I read the "Lunar Chronicles," its like this ..... in my head every thing is still happening with cinder and winter and scarlet lets not forget cress. These characters were my best friends from 8:30pm to 11pm they were my escape from my beautiful loving children that scream at me how much they love me. I need their story to continue. I have tried to read "First & Then" but it was not my style all the way around I ended up reading about two chapters and walking away from it. then I tried to read "Mechanica" which is a retelling of a fairy tail (great right up my ally) no epic flop. Then "Mangolia" which I will say was interesting but kind of morbid. girl in the book is dying then dies and then ends up not dying but really living in a ship above the clouds while her super smart friend tried epically to find her against all crazy town remarks from his two moms. I have to say its one of the first books where I read about someone having two moms and was adopted (whoo hoo for culture change in books!!!!) but ultimately it was way too far stretched and to say that she was part bird was odd. I just couldn't get into it. Lucky me though my copy of the Glass Sword came in and I am ecstatic to read it!!! until then!!!
