Recently I finished Defending Jacob by William Landay. I've been lucky to read such interesting books lately. I would definitely recommend this novel.
It's about a father, Andy Barber who is an assistant district attorney. A young teenager is murdered and Andy takes on the case. The boy was a classmate of Andy's son who eventually becomes the primary suspect in the case. Following the investigation and the trial is exciting and juicy.
Andy believes in His son's innocence but as a reader you have to decide for yourself.

The installation design of OPGW should consider the coordination of wire stress, sag and insulation clearance, and the load should not exceed the allowable use range of the existing tower and foundation. Therefore, the characteristic curve should be calculated according to the OPGW main technical parameters selected, and combined with the actual engineering design of junction box, all kinds of fittings, accessories layout, appearance and installation drawings.
