I have all but finished this book, it's a good read as far as the genre is concerned with characters that do make you care about them. However you have to read all her books in order, otherwise the relationships won't make any sense at all, I've read all of them in order. A new twist in this particular novel is that one of the characters has diabetes. Unfortunately Karin gets it nearly right but not quite. Faith has a child of 4 months and has had diabetes a year - so you'd assume this might be gestational diabetes, but 4 months after the birth she's on insulin. You see the first hypo coming... and the reason Faith doesn't have it sooner rather than later is due to an adrenalin rush, followed by a fairly serious hypo which she herself doesn't recognise. She carries her glucagon kit and her meter in her handbag, but her insulin at home in her fridge and has nothing with which to counter a hypo in the way of fast glucose. A dr on the scene injects the glucagon, even though she is capable of drinking coke (and has already done so). The Dr calls this an "Insulin reaction" rather than a hypo. Later she takes the vial of insulin out of the fridge and using a syringe injects it before eating a "nutrition bar" and nothing else. So it goes.... she takes insulin to stop her BGs "bouncing around" though actually lack of insulin in my experience makes BGs bounce only one way... up. Later on the she arrives at the Dr's home having bought herself some insulin pens at the pharmacy - no mention of needles - and the Dr asks her to test. The Dr tuts when the result is 135 (7.5) and immediately "dials the correct dose" and injects Faith. Pardon?
Karin as a respected author you could have researched this just a little better - even half an hour looking on a diabetes forum would have informed you better than you are! Plus you could have asked a Dr. You could still have used the highs and hypos to suit your plot, but it would have been more believable
